Aright square prism has a volume of 360 cubic units.

which could be the dimensions, in units, of the prism? check all that apply.

a. 3 by 3 by 40
b. 4 by 4 by 20
c. 6 by 6 by 10
d. 2.5 by 12 by 12
e. 3.6 by 10 by 10

So basically we can check them all by multiplying all of the dimensions.
A: 3 * 3 * 40 = 360, so yes, it could be the dimensions
B: 4 * 4 * 20 = 320, so no, it couldn't be the dimensions
C: 6 * 6 * 10 = 360, so yes, it could be the dimensions.
D: 2.5 * 12 * 12 = 360, so yes, it could be the dimensions.
E: 3.6 * 10 * 10 = 360, so yes, it could be the dimensions.

I hope this helped :)
