Answer:
840 cm^3
Step-by-step explanation:
L x W x H = V
Split the prism into 2 different prisms.
6 is constant throughout the figure, so all we have to do is find the L and H of the two prisms and multiply them by 6.
15 x 8 = 120
The height of the higher prism can be determined by subtracting the bottom height from the total height.
12 - 8 = 4
5 x 4 = 20
Add the two side areas together.
20 + 120 = 140
Multiply by the width, 6.
140 x 6 = 840
