The total volume of the wedding cake would be 620 in³.
A rectangular prism is a three-dimensional shape. It also known as a cuboid.
Volume = length x width x height
The volume of the cake is the sum of the volume of the three layers.
Volume of the first layer = 2 1/2 x 12 x 10
5/2 x 12 x 10 = 300 in³
Volume of the second layer = 2 1/2 x 10 x 8
5/2 x 10 x 8 = 200 in³
Volume of the third layer = 2 1/2 x 8 x 6
= 5/2 x 8 x 6 = 120 in³
Total volume = 300 + 200 + 120 = 620 in³
