Width- 3 inches
Height- 11 inches
Surface area- I think its 290 inches^2
Volume- 264 inches^2 (I think)

Answer 1

You are right, with the total surface. next thing u want to do is multiply 290 and 0.05 and you should get your answer

Answer 2

The manufacturing cost is $14.50

Explanation:

To calculate the cost for manufacturing a standard cereal box, we must take in account its surface area. The volume will be used to estimate the amount of cereal, the box can contain. The box is a cuboid as standard cereal boxes are cuboid.

So, we will consider the surface area. Given are:

Length- 8 inches

Width- 3 inches

Height- 11 inches

We will find the surface area as :
`2lw+2wh+2lh`

=
`(2*8*3)+(2*3*11)+(2*8*11)`

=
`48+66+176=290` square inches

Given is - the cost of manufacturing the box is $0.05 per square inch.

So, cost of manufacturing the box with 290 square inches area =

`0.05*290=14.50` dollars.

The answer is $14.50
