Answer:
34 Cubes
Step-by-step explanation:
<u>Step 1: </u>Find the Volume of the Rectangular Prism
The dimensions of the rectangular prism are: 225 inches by 315 inches by 2 inches.
Volume of the Rectangular Prism = 225*315*2=141750 Cubic Inches
<u>Step 2:</u> Find the Volume of the Cube
Edge length of the cube, s=15 Inch
Volume of a Cube =
Volume==3375 Cubic Inches
<u>Step 3: </u>Determine how many cubes fit in the prism
To find out how many cubes fit in the rectangular prism, divide the volume of the rectangular prism by the volume of the cube.
Number of Cubes =Volume of the Rectangular Prism ÷ Volume of Cube
=141750 ÷ 3375
=34
34 Cubes will fit in the rectangular prism.
The amount of energy waste, in terms of hours which a 60-watt light bulb would remain on, is 61.6 hours then the correct option is B.
<h3>What are ratio and proportion?</h3>A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Marco leaves the bathroom faucet running for 22 minutes while he gets ready in the morning.
Running the faucet for 5 minutes wastes the same amount of energy as leaving a 60-watt light bulb on for 14 hours.
Then we have
So, the rate is 2.8 hours per minute.
Since macro leaves the bathroom faucet running for 22 minutes. Then the waste of energy is leaving a 60-watt light bulb will be
→22 minutes × 2.8 hours/minute = 61.6 hours.
