1. To solve this exercise you must apply the formula for calculate the volume of a rectangular prism and the formula for calculate the volume of a rectangular pyramid:
2. Volume the rectangular prism:
V1=LxWxH
V1=(7 in)(3 in)(4 in)
V1=84 in³
3. Volume of the rectangular pyramid:
V2=BxH/3
B=(7 in)(3 in)=21 in
H=12 in-4 in=8 in
V2=(21 in)(8 in)/3
V2=56 in³
4. The volume of the composite figure is
V=V1+V2
V=140 in³

Answer:
First: 15
Second: 21
Third: 45
Step-by-step explanation:
In order to create the equation we need to represent the evenings with an alebraic term, in thsi case we are going to represent the second evening with an X
Second evening:x
The first night she got 6 fewer calls than the second: Second-6=x-6
The third night she received 3 times the first: 3(first night)=3(x-6)
The equation is First Night plus second night plus third night equals 81.
So the first evening he received 15 calls, the second he received 21 and the third one he received 45.
