Question

I bought a box of granola bars at the store that has a volume of 210 cubic centimeters. Which of the following could be the dimensions of my box? Choose all answers that apply: A) 15cm, 2cm, 7cm B)14cm, 3cm, 7cm C) 7cm, 3cm, 10cm

Answer 1

Your answer would be C

Answer 2

The following is the formula for volume:

$V=lwh$

The easiest way to solve this problem would be to plug in each answer. Let's try them all.

A.) $(15cm)(2cm)(7cm)=210cm^3$

B.) $(14cm)(3cm)(7cm)=294cm^3$

C.) $(7cm)(3cm)(10cm)=210cm^3$

We can eliminate B since it does not equal 210 cubic centimeters $(cm^3)$. By the way, the reason we get cubic centimeters $(cm^3)$, is because we multiply cm*cm*cm.

Your answers would be A and C, since they both equal $210cm^3$.
