Answer:
The volume of the rectangular prism is 57.6in³
Step-by-step explanation:
First of all we need to calculate the area of the triangle, as the triangle has two 45 ° angles this means that it has 2 equal legs
a = area
a = (8in * 8in) / 2
a = 64in²/2
a = 32in²
To calculate the volume of a rectangular prism we have to use the following formula:
a = area = 32 in²
v = volume
h = height = 1.8in
v = a * h
we replace the values that we know
v = 32in² * 1.8in
v = 57.6in³
The volume of the rectangular prism is 57.6in³
