Answer 1

It's 580 (I did it on khan and got it correct)

Explanation:

Answer 2

The surface area of cereal box is 580 square units, if the height is 20 the width is 3 and the length is 10.

Explanation:

The given is,

Cereal box has a shape of rectangular prism

Height is 20

Width is 3

Length is 10

Step: 1

Formula to calculate the surface area of the rectangular prism,

`A = 2 ( lw+wh +hl)`......................(1)

Where, l - Length

w - Width

h - Height

Step: 2

From the given,

h = 20

w = 3

l = 10

Equation (1) becomes,

`A = 2 ( (10)(3)+(3)(20)+(20)(10))`

= 2 ( 30 + 60 + 200 )

A = 580 square units

Result:

The surface area of cereal box is 580 square units, if the height is 20 the width is 3 and the length is 10.
