Drag each volume of a prism to match a rectangular prism on the left with the given dimensions.
Triss [41]

The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³

<h3>What is volume?</h3>

Volume is the amount of space occupied by a three dimensional shape or object.

The volume of a rectangular prism is given by:

Volume = length * width * height

a) Dimensions: 4 in., 3 in., 6 in.

Volume = 4 * 3 * 6 = 72 in³

b) Dimensions: 6 in., 3 in., 2 in.

Volume = 6 * 3 * 2 = 36 in³

c) Dimensions: 4 in., 5 in., 4 in.

Volume = 4 * 5 * 4 = 80 in³

d) Dimensions: 2 in., 9 in., 3 in.

Volume = 2 * 9 * 3 = 54 in³

The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³

Christopher works at the power plant for the southwest part of his home state. For peak operational performance, his department
kirza4 [7]
<h2>Answer:150 electricians,10 inspectors</h2>

Step-by-step explanation:

The solution uses unitary method.

The unitary method is a method for solving a problem by first finding the value of a single unit and finding the required value by multiplying the single unit value.

Given,

Each generator employs 3 electricians.

Every 60 electricians require 4 inspectors.

So,every electrician require \frac{4}{60}=\frac{1}{15} inspectors.

Anthony's department has 50 generators.

Since each generator requires 3 electricians,50 generators require 3\times 50=150 electricians.

Since each electrician needs \frac{1}{15} inspectors,150 electricians need \frac{1}{15} \times 150=10 inspectors.

So,to maintain peak performance Antony's department requires 150 electricians and 10 inspectors.
