Part 1
Find the volume of a rectangular pyramid with base 17 m2 and height 5 m. Find the result to the nearest unit.

1 answer

To find the volume \( V \) of a rectangular pyramid, you can use the formula:

\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} \]

In this case:

  • The base area is given as \( 17 , \text{m}^2 \)
  • The height is given as \( 5 , \text{m} \)

Plugging in the values:

\[ V = \frac{1}{3} \times 17 , \text{m}^2 \times 5 , \text{m} \]

Calculating this step-by-step:

  1. Multiply the base area by the height: \[ 17 , \text{m}^2 \times 5 , \text{m} = 85 , \text{m}^3 \]

  2. Now multiply by \( \frac{1}{3} \): \[ V = \frac{1}{3} \times 85 , \text{m}^3 = \frac{85}{3} , \text{m}^3 \approx 28.33 , \text{m}^3 \]

Finally, rounding to the nearest unit:

\[ V \approx 28 , \text{m}^3 \]

Therefore, the volume of the rectangular pyramid is approximately 28 m³.
