Question

PLEASE HELP!!!!!!!!

Answer 1

32 cm long

15 cm wide

6 cm tall

 

The surface area is the sum of the area of all six sides

 

Two sides are 32 x 15

Two sides are 15 x 6

Two sides are 6 x 32

 

32 x 15 = 480

15 x 6 = 90

6 x 32 = 192

 

Surface area = 2(480) + 2(90) + 2(192) = 960 + 180 + 384 = 1524 cm2

Answer 2

Answer:

• 1044 cm²

Step-by-step explanation:

Since the box doesn't have the top, the total surface area includes 4 sides and the bottom.

• S = 32(15) + 2(32 + 15)(6) = 1044 cm²

Cardboard used is 1044 cm²
