If the surface area of a certain cube is 2400, what is its volume?
A. 8000(√6)^3
B. 1000(√6)^3
C. 8000
D. 6400
E. 4000
The OA is C.
We know that the surface area of a cube is 6s^2, then
$$6s^2=2400\ \Rightarrow s^2=400\ \Rightarrow s=20$$
Also, we know that the volume of a cube is s^3, then
$$s^3=20^3=8000$$
Experts, any suggestion about this PS question? Thanks in advance.
