Question

A candy bar box is in the shape of a triangular prism. The volume of the box is 1,200 cubic centimeters.

Answer 1

Part A:

13²-5²=c

169-25=144

√144=12

Your height is 12.

Part B:

Base:

20(10)=200

Two triangular faces:

5(13)=65

65(2)=130

Rectangular faces:

20(13)=260

260(2)=520

200+130+520=850

They would need 850 cm of cardboard.

Hope this helps! Have an amazing day!
