A prism has a pentagonal base. The area of the pentagon is 45 cm2, the
height of the prism is 13 cm. Find the
volume of the prism.

585

Step-by-step explanation:

45 x 13 = 585

Let me explain...

we don't know the length and the width but it is telling us that there is an area of 45 centimeters. Meaning the Length x Width is equal to the area. so there wasn't no need to solve for length and width.

So that's why we only had to multiply the 45  (Length x width) and the height which is 13.

Final 585

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
