1. A cube has 6 equal sides so all you have to do is take that number and multiply it three times like this:

V = (s)(s)(s).

So for a cube with sides of 10in, the Volume would be:

V = (10in)(10in)(10in) → 1000in3

2. For a rectangular prism (remember the formula is V = lwh)

Find the volume for a prism with a length of 12in, a width of 5in, and a height of 3in.

All we do is plug in all three of these numbers into the formula and multiply.

V = (12in)(5in)(3in) = 180in3

3. For a cylinder (formula V = ∏r2h) with a radius of 6.1m and a height of 15m, what would the volume be?

Let's plug ‘r’ = 6.1m and ‘h’ = 15m into the formula and calculate.

V = ∏(6.1m)2(15m)

V → ∏(37.21)(15)

V → 558.15m3∏
