Question

What is the volume of the prism?

Answer 1

Answer:

40 $\frac{5}{8}$ $cm^{3}$

Step-by-step explanation:

The figure is a rectangular prism, so the formula would be Volume = length x width x height.

length =  6 $\frac{1}{2}$ cm

width  =  2 $\frac{1}{2}$ cm

height  =  2 $\frac{1}{2}$ cm

If you plug everything you have in the problem into the volume equation, you would get : Volume = 6 $\frac{1}{2}$ cm x 2 $\frac{1}{2}$ cm x 2 $\frac{1}{2}$ cm.

Without a calculator, I would first turn the mixed numbers into improper fractions.

• 6 $\frac{1}{2}$  = $\frac{13}{2}$

• 2 $\frac{1}{2}$ = $\frac{5}{2}$

Volume = $\frac{13}{2}$ x  $\frac{5}{2}$ x  $\frac{5}{2}$

When you multiply everything together you should get $\frac{325}{8}$.

As a mixed number, that would be 40 $\frac{5}{8}$ $cm^{3}$.
