Answer:
Step-by-step explanation:
That is correct.
P=4s=4(12)=48in
A=s^2=12^2=144in^2
Volume of rectangular prism = length * width * height
Volume of triangular prism =( length * height * base )/2
Given,
Volume of rectangular prism = 18 + volume of triangular prism

18x = 18+14x
4x=18
x= 4.5 ft
So volume of rectangular prism = 6* 4.5* 3 = 81 ft³
Volume of triangular prism = (7* 4.5 * 4) / 2 = 63 ft³

Answer:
- fraction 3 and 3 over 5 cubic feet
Step-by-step explanation:
Volume formula V= lwh
<u>Given</u>
- l = 2 2/3 = 8/3 ft
- w = 1 1/8 = 9/8 ft
- h = 1 1/5 = 6/5 ft
<u>Volume is:</u>
- V = 8/3*9/8*6/5 =18/5 = 3 3/5 ft³
Correct option is A
