EXPLANATION

The first figure is a triangular prism, so the equation that applies to find the volume is

[tex]Volume=\frac{1}{2}\text{bhl}[/tex]

In this case, b=3 inches L= 6 2/3 inches = 20/3 inches h= 4 1/3 inches = 13/3 inches.

Replacing terms:

[tex]\text{Volume}=\frac{1}{2}\cdot3\cdot\frac{13}{3}\cdot\frac{20}{3}[/tex]

Multiplying the fractions:

[tex]\text{Volume}=\frac{130}{3}=43.3in^3[/tex]

The answer is the OPTION B: 43.3 inches^3
