Answers

a rectangular right prism area=legnth times width times height or base area times height

base=3 b y12, area=3 times 12=36
height=5
36 times 5=180

an oblique rectangular prism volume is the same as the right rectangular prism formula so
4 times 9 times 5=180

180=180
the volumes are the same

Answer

Find out the what will their monthly income be .

To proof

Let us assume that the their monthly income be x .

As given

x = 350 + 2* 350 + 400

x = 350 + 700 + 400

x= $1450

Therefore  monthly income be $1450 .

Option (D) is correct .

Hence proved

350+(2*350)+400=1450
