Bases are squares with sides that measure 27 inches. the height is 12 inches.

Part 1)

Part 2)

Step-by-step explanation:

The correct question is

Find the volume and the surface area of a rectangular prism. Bases are squares with sides that measure 27 inches. The height is 12 inches.

Part 1) Find the volume of the prism

The volume of the prism is equal to

where

B is the area of the base

h is the height of the prism

Find the area of the base B

---> the base is a square

we have

substitute

Part 2) Find the surface area of the prism

The surface area of the prism is equal to

where

B is the area of the base

P is the perimeter of the base

h is the height of the prism

Find the perimeter of the base P

substitute the values in the formula

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
