We can see that
There are four triangle on the surface
and five squares
For finding surface areas , we will find area of each surface and then add them
Calculation of area of triangle:
We are given
base=b=8
height=h=10
now, we can use area formula
[tex] A=\frac{1}{2}*b*h [/tex]
[tex] A=\frac{1}{2}*8*10 [/tex]
[tex] A=40 [/tex]
Calculation of area of square:
base=width=8
[tex] A=8*8 [/tex]
[tex] A=64 [/tex]
There are four triangle and five squares on the surface
so, we can find surface area
SA=4* triangle + 5*square
[tex] SA=4*40+5*64 [/tex]
[tex] SA=480ft^2 [/tex]
so, surface area is [tex] 480ft^2 [/tex].............Answer
