Question 1: Find the surface area of a cube whose side measure 10 cm. Solution: A cuboid is a 3D solid which has six square surfaces. The surface area of a cube = 6 a 2 = 6 (10 cm) 2 = 6 x 100 cm 2 = 600 cm 2. Surface area of the cube is 600 cm 2. Question 2: Find the cost of painting the walls of a room whose dimensions are 15 ft x 12 ft x 10 ft at the rate of $\$$ 8 per square feet.
