Question

the net for a candy box is shown.if the triangular ends of the Box are torn off, What is the remaining surface area of the candy Box?

Answer 1

Without the tringles, we will have 3 rectangles

The formula of the area of a rectangle

`A_R=l* w`

for the first rectangle

l=10 in

w=6 in

`A_(R1)=10*6=60in^2`

for the second rectangle and third rectangle

l=10in

w=5 in

`A_(R2)=10*5=50in^2`

the remaining surface area is

`SA=A_(R1)+2A_(R2)=60+2(50)_{}=60+100=160in^2`

the remaining surface area is 160 in^2
