What is the volume of the prism?

Solution

To find the volume of the prism in the given image, we need to identify the shape of the base and the height of the prism. The base of this prism is a trapezoid, and the height of the prism is given as 5 inches.

The formula for the volume VV of a prism is:

V=B×hV = B \times h

where BB is the area of the base and hh is the height of the prism.

First, let's find the area of the trapezoidal base. The formula for the area AA of a trapezoid is:

A=12×(a+b)×hbA = \frac{1}{2} \times (a + b) \times h_b

where aa and bb are the lengths of the parallel sides of the trapezoid, and hbh_b is the height of the trapezoid.

In this image:

  • a=4.7a = 4.7 inches (top base of the trapezoid)
  • b=4.7b = 4.7 inches (bottom base of the trapezoid)
  • hb=5.2h_b = 5.2 inches (height of the trapezoid)

So, the area of the trapezoid is:

A=12×(4.7+4.7)×5.2A = \frac{1}{2} \times (4.7 + 4.7) \times 5.2 A=12×9.4×5.2A = \frac{1}{2} \times 9.4 \times 5.2 A=12×48.88A = \frac{1}{2} \times 48.88 A=24.44 square inchesA = 24.44 \text{ square inches}

Now, we can find the volume of the prism:

V=24.44×5V = 24.44 \times 5 V=122.2 cubic inchesV = 122.2 \text{ cubic inches}

So, the volume of the prism is 122.2122.2 cubic inches.
