the edges of three metal cubes are 4 cm , 5 cm , and 6 cm respectively . a new cube is made by melting these three cubes together . what is the edge of the new cube ( in centimeters ) ?
"the total volume is 4 ^ 3 + 5 ^ 3 + 6 ^ 3 = 405 the edge of the new cube is the cube root of 405 which is about 7.4 cm . the answer is e ."
power(add(power(6, 5), add(4, power(5, 5))), const_0_33)
