Math Problem Statement

A triangular prism has a height of 8 centimeters (cm) and a volume of 216 cm³. What is the area, in cm², of the base of the prism? (The volume of a triangular prism is equal to Bh, where B is the area of the base and h is the height of the prism.)

Solution

The problem provided involves a triangular prism with the following known values:

  • Height (h) = 8 cm
  • Volume (V) = 216 cm³

The formula for the volume of a triangular prism is given as:

V=B×hV = B \times h

Where:

  • VV is the volume of the prism,
  • BB is the area of the triangular base, and
  • hh is the height of the prism.

We need to find the area of the base BB. To do so, we rearrange the formula to solve for BB:

B=VhB = \frac{V}{h}

Substituting the known values:

B=216cm38cm=27cm2B = \frac{216 \, \text{cm}^3}{8 \, \text{cm}} = 27 \, \text{cm}^2

Thus, the area of the base of the triangular prism is 27 cm².
