Question

The diagram shows the net of a juice box. The box is a rectangular prism. What is the surface area of the juice box?

Answer 1

Given:

The diagram shows the net of a juice box.

The box is a rectangular prism.

The length of the prism is 6.4 cm.

The width of the prism is 4 cm.

The height of the prism is 10.5 cm.

We need to determine the surface area of the juice box.

Surface area of the juice box:

The surface area of the juice box can be determined using the formula,

`SA=2(w l+h l+h w)`

Substituting the values, we get;

`SA=2[(4* 6.4)+(10.5 * 6.4 )+(10.5 * 4)]`

`SA=2(25.6+67.2+42)`

`SA=2(134.8)`

`SA=269.6 \ cm^2`

Thus, the surface area of the juice box is 269.6 cm²
