Question: Does Lake Yojoa or Lake Volta have a larger surface area?
Context: Lake Roy is a natural freshwater lake inside the city of Winter Haven, Florida.  It has a 74.17 acre surface area and is located on the south side of Cypress Gardens Boulevard.  The lake once had a larger surface area, but when Cypress Gardens Boulevard was upgraded it ran over some of the northern part of Lake Roy; this part had been filled so the road could be rerouted.  A small part of the old lakebed is north of the street, but is more of a retention pond now, for the most part remaining dry.  The lake is of an irregular shape.  Lake Roy is connected by a canal on its southwest side to Lake Lulu and indirectly from there to more than twenty other area lakes.  These lakes are linked by canals and are known locally as the Chain of Lakes.  Most of the shore of Lake Roy is bordered by residential housing.  Residential areas circle from the southeast around to the northwest side of the lake.  Along Cypress Gardens Boulevard on the northwest are businesses and a hotel, Lake Roy Beach Inn, is on this street at the northeast corner of the lake. Lake Yojoa is the largest lake in Honduras with a surface area of 79 square kilometers (30.50 mi²) and an average depth of 15 meters (50 ft).  At an altitude of 700 meters (2,300 ft), it lies in a depression formed by volcanoes.  The Lake Yojoa volcanic field consists of Pleistocene to Holocene scoria cones, craters, and lava flows. Lake Titicaca (Spanish: "Lago Titicaca" , Quechua: "Titiqaqa Qucha" ) is a large, deep lake in the Andes on the border of Bolivia and Peru.  By volume of water and by surface area, it is the largest lake in South America.  Lake Maracaibo has a larger surface area, but it is a tidal bay, not a lake. Brunauer–Emmett–Teller (BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area of materials.  In 1938, Stephen Brunauer, Paul Hugh Emmett, and Edward Teller published the first article about the BET theory in the Journal of the American Chemical Society.  The BET theory applies to systems of multilayer adsorption and usually utilizes probing gases that do not chemically react with material surfaces as adsorbates to quantify specific surface area.  Nitrogen is the most commonly employed gaseous adsorbate used for surface probing by BET methods.  For this reason, standard BET analysis is most often conducted at the boiling temperature of N (77 K).  Further probing adsorbates are also utilized, albeit with lower frequency, allowing the measurement of surface area at different temperatures and measurement scales.  These have included argon, carbon dioxide, and water.  Specific surface area is a scale-dependent property, with no single true value of specific surface area definable, and thus quantities of specific surface area determined through BET theory may depend on the adsorbate molecule utilized and its adsorption cross section. The surface area of a solid object is a measure of the total area that the surface of the object occupies.  The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces.  Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces.  This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration. Lake Taupo is a lake in the North Island of New Zealand.  It is in the caldera of the Taupo Volcano.  With a surface area of 616 km2 , it is the largest lake by surface area in New Zealand, and the second largest freshwater lake by surface area in geopolitical Oceania after Lake Murray (Papua New Guinea).  Motutaiko Island lies in the south east area of the lake. Lake Volta is a large reservoir contained behind the Akosombo Dam.  It is completely within the country of Ghana and has a surface area of 8,502 km2 . Los Naranjos is the name for an archaeological region in western Honduras.  It lies on the north border of Lake Yojoa.  It is significant to the region because of its implications on determining where the Mayan frontier existed, as well as which ancient peoples were in contact and what relations between "tribes" may have been like.  Whether or not the Maya influenced the people of the Lake Yojoa region is disputed. The Akosombo Dam, also known as the Volta Dam, is a hydroelectric dam on the Volta River in southeastern Ghana in the Akosombo gorge and part of the Volta River Authority.  The construction of the dam flooded part of the Volta River Basin, and led to the subsequent creation of Lake Volta.  Lake Volta is the largest man-made lake in the world by surface area.  It covers 8502 km2 , which is 3.6% of Ghana's land area.  With a volume of 148 cubic kilometers Lake Volta is the world's third largest man-made lake by volume, the largest being Lake Kariba which is located between Zimbabwe and Zambia in Southern Africa and contains 185 cubic kilometers of water. This is a listing of the reservoirs (artificial lakes) in the world with a surface area exceeding 500 km2 .  Reservoirs can be formed conventionally, by damming the outlet of a canyon or valley to form a lake; the largest of this type is Ghana's Lake Volta, with a water surface of 8500 km2 .  Reservoirs can also be formed by damming the outlets of natural lakes to regulate water levels, such as those at Uganda's Owen Falls Dam (Lake Victoria) and Russia's Irkutsk Dam (Lake Baikal).  These are included and indicated with light blue cell background.
