The volume of the prism is 300 cubic inches not 300 square inches
Step-by-step explanation:
we know that
The volume of the prism is equal to

where
B is the area of the base
h is the height of the prism
we have

substitute

therefore
The volume of the prism is 300 cubic inches not 300 square inches

Answer:
8, 15 and 17 feet respectively
Step-by-step explanation:
Let the shorter leg=l feet
The longer leg of a right triangle is 7 ft longer than the shorter leg, therefore Length of the longer leg=(l+7) feet
The hypotenuse is 9ft longer than the shorter leg. Therefore Length of the hypotenuse=(l+9) feet
Using Pythagoras Theorem

This results into:


l-8=0 or l+4=0
l=8 or -4
Since length cannot be negative, The length l=8 feet
The sides of the rectangle are therefore: 8, 15 and 17 feet respectively
