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=(1)/(2)*b*h`

`A=(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
