What is the volume of a pyramid that has a height of 32 cm, a base length of 15 cm, and an apothem length of 9 cm?

Calculating the Volume of the Pyramid

To find the volume of a pyramid, we can use the formula:

Volume (V) = (1/3) × Base Area (B) × Height (h)

Where:

  • Base Area (B) is the area of the base of the pyramid.
  • Height (h) is the perpendicular height from the base to the apex of the pyramid.

Step 1: Calculate the Base Area

Given that the base is square with a side length of 15 cm, we can calculate the base area (B) as follows:

B = side × side = 15 cm × 15 cm = 225 cm²

Step 2: Volume Calculation

Now we can plug the values into the volume formula:

V = (1/3) × B × h
V = (1/3) × 225 cm² × 32 cm

Calculating this gives:

V = (1/3) × 7200 cm³ = 2400 cm³

Conclusion

The volume of the pyramid with a height of 32 cm and a base length of 15 cm is 2400 cm³.
