1 answer:
Ivanshal [37]3 years ago
3 0

Answer:

Step-by-step explanation:

(-14+\frac{3}{2}b)-(1+\frac{8}{2}b)=-14-1+\frac{3}{2}b-4b

                                   = (-15-\frac{5}{2}b)

(5+2b)+(2b+\frac{3}{2})=(5+\frac{3}{2})+(2b+2b)

                             = (4b+\frac{13}{2})

(\frac{7}{2}b-3)-(8+6b) = (\frac{7}{2}b-6b)-(3+8)

                             = (-\frac{5}{2}b-11)

(-10+b)+(7b-5)=(-10-5)+(b+7b)

                               = (8b-15)

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.
