Question

Sarai wrapped a soccer

Answer 1

Answer:

624 square inches of  cardboard were used to make the box.

Step-by-step explanation:

Slant height of the box = l = 20 inches

Side of the base of the box = s = 12 inch

Area of the base = $s^2$

Area of triangular face = $\frac{1}{2}\times s\time l$

There are 4 triangle faces, and single square base , so the total area is :

$T=s^2+4\times \frac{1}{2}s\times h$

$=(12 inch)^2+4\times \frac{1}{2}\times 12 inch\times 20 inch$

$T=624 inch^2$

624 square inches of  cardboard were used to make the box.
