Question

A manufacturer uses a mold to make a part in the shape of a triangular prism. The dimensions of this part are shown below Calculate the volume of the part. Round your answer to the nearest whole numberLength l =10.75

Answer 1

The dimension of the prism are,

Base, b = 12.6

Height, h = 1.6

Length, L= 10.75.

The formula for the volume of triangular prism is,

$V=\frac{1}{2}\cdot b\cdot h\cdot l$

Substitute the values in the formula to obtain the volume of prism.

$\begin{gathered} V=\frac{1}{2}\cdot12.6\cdot1.6\cdot10.75 \\ =\frac{216.72}{2} \\ =108.36 \\ \approx108 \end{gathered}$

So volume is 108 millimeter cube.
