What is the height of the triangular prism below if the volume equals 1,638 cubic millimeters? 65 mm 63 mm 26 mm 28 mm.
sergejj [24]

Answer:

The height of the triangular prism is 26\ mm

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The volume of the triangular prism is equal to

V=Bh

where

B is the area of the triangular base

h is the height of the prism

<em>Find the area of the base B</em>

B=\frac{1}{2}(7)(18)=63\ mm^{2}

we have

V=1,638\ mm^{3}

h=x\ mm

substitute and solve for x

1,638=(63)x

x=1,638/(63)=26\ mm
