Hilary want to fill a mini cake pan with batter to make a mini cake for philip's party. the cake pan is 4.0 inches long, 9.0 inches wide, and 2.2 inches
deep. whats the volume of the cake pan?

The formula to solve for the volume (V) of a rectangular prism is,

                                           V = L x W x H

where L is the length, W is width, and H the height or depth.

Substituting the known dimensions on the equation above,
 
                             V = (4 in) x (9 in) x (2.2 in) = 79.2 in^3

Thus, the volume of the cake pan is 79.2 in^3.
