Answer: $552
(20x12) 2 =480
480 x 0.60 = 228
480-228=552
Answer:
Lateral Surface Area: 56 in²
Total Surface Area: 81 in²
Step-by-step explanation:
To find the lateral surface area, all we need to do is find the surface area for one of the lateral faces and then multiply it by 4.
![\frac{1}{2} *b*h](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2Ab%2Ah)
![\frac{1}{2} *5*5.6=2.5*5.6=14](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A5%2A5.6%3D2.5%2A5.6%3D14)
Now the area of all the lateral faces:
14*4=56
The total surface area is the lateral area plus the base.
56+(5*5)=56+25=81
