Question

​a) Find the volume of the shaded figure by subtracting the smaller volume from the larger. The formula for the volume of a rectangular solid is V=lwh. ​b) Write the expression obtained in part ​a) in factored form.

Answer 1

Part A - 2a*2b Part B- 2(a*b)

Explanation:

Part A)

V=lwh of larger prism - lwh of smaller prism

=9a*a*a-9a*b*b

=11a-9a*2b

=2a*2b

Part B)

2a*2b

=2(a*b)
