Question

Anslee is designing a doll house shaped like a rectangular prism. The doll house is 8 feet long, 2 feet wide and 3 feet high. What is the surface area of the doll house?

Answer 1

We know that
L=8 ft
W=2 ft
H=3 ft
[surface area of the doll house]=2*[W*H]+2*[L*H]+2*[W*L]
[surface area of the doll house]=2*[2*3]+2*[8*3]+2*[2*8]
[surface area of the doll house]=2*[6]+2*[24]+2*[16]
[surface area of the doll house]=12+48+32--------> 92 ft²

the answer is 92 ft²
