Answer

B

Explanation

Plug the volume, length, and width into the formula for the volume of a box:

V=lwh10x^{2}= (2x)(3x)h10x^{2}=6x^{2}h

Divide both sides by 6x^{2}:

\dfrac{10}{6}=h\dfrac{5}{3}=h

Therefore, the right answer is (B).

V=lwh10x^{2}= (2x)(3x)h10x^{2}=6x^{2}h

Divide both sides by 6x^{2}:

\dfrac{10}{6}=h\dfrac{5}{3}=h

Therefore, the right answer is (B).
