Question

Find the volume of the pyramid. round to the nearest hundredth

Answer 1

A. 17.35 mm³

Explanation:

Volume of a Pyramid

`V = (1)/(3)Bh`

V ... volume

B ... area of base

h ... height

The base of this pyramid is a square. Area of a square is side times side.

`B = 3.5 * 3.5`

Let's substitute in the formula.

`V = (1)/(3)Bh\\\\V = (1)/(3)(3.5* 3.5)(4.25)\\\\V = (1)/(3)(12.25)(4.25)\\\\V \approx 17.35417 \text{ mm}^3`

Now let's round to the nearest hundredth.

V = 17.35 mm³
