Question

Whats the suface area?

Answer 1

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

$A=\frac{1}{2}*b*h$

$A=\frac{1}{2}*8*10$

$A=40$

Calculation of area of square:

base=width=8

$A=8*8$

$A=64$

There are four triangle and five squares on the surface

so, we can find surface area

SA=4* triangle + 5*square

$SA=4*40+5*64$

$SA=480ft^2$

so, surface area is $480ft^2$.............Answer
