The problem tells you this shape is the BASE of the bird feeder, which is 8 inches away from the other base. So we want to find the area of the shape and multiply it by it’s “height” of 8 inches.
To get area of the shape break it in two and find the area of the rectangle and the area of the triangle and add together.
area of a rectangle = length x width a = 7 x 5 a = 35
area of a triangle = 1/2 base x height a = 1/2 x 7 x 4 a = 14
area of shape = area of rectangle + area of triangle = 35 + 14 = 49
Volume of bird feeder = area of base x height = 49 x 8 = 392
The answer is: The volume of the bird feeder is 392 inches^3
