Question

A pedestal in a craft store is in the shape

Answer 1

Answer:

Step-by-step explanation:

Robert sketches two rectangular prisms, A and B.

Prism A’s side lengths are 5 centimeters, 6 centimeters, and 7 centimeters.

Prism B’s side lengths were twice those of prism A’s: 10 centimeters,

12 centimeters, and 14 centimeters. Robert says the surface area of

prism B is twice the surface area of prism A. Is he correct? If he is not,

how many times as great as prism A’s surface area is prism B’s surface

area? Show your work.

Answer 2

Given:
side lengths of right triangles = 12 cm ; 16 cm ; 20 cm
lateral area = 192 cm²

lateral area of a triangular prism = perimeter * height
192 cm² = (12 cm + 16 cm + 20 cm) * height
192 cm² = 48 cm * height
192 cm² / 48 cm = height
4 cm = height

The height of the pedestal in the shape of a triangular prism is 4 cm.
