Question

The volume of a cube is 521 cm3. calculate the total surface area in cm2​

Answer 1

Answer: If the volume is actually 512 cm^3, the surface area is 384 cm^2.

Step-by-step explanation: Take the cube root of 512 to get the length of one edge of the cube. That is 8

Square 8 to get the area of one face. That's 64

There are 6 faces, so multiply 6×64=384 cm^2

If the volume really was 521, the procedure is the same, but the numbers have decimals. So more complicated calculations.

Answer 2

262 cm............................
