Explanation:
<u>1. Volume of a cup</u>
The shape of the cup is a cylinder. The volume of a cylinder is:

The diameter fo the cup is half the diameter: 2in/2 = 1in.
Substitute radius = 1 in, and height = 4 in in the formula for the volume of a cylinder:

<u>2. Volume of the sink:</u>
The volume of the sink is 1072in³ (note the units is in³ and not in).
<u>3. Divide the volume of the sink by the volume of the cup.</u>
This gives the number of cups that contain a volume equal to the volume of the sink:

Answer:
371 pounds
Step-by-step explanation:
First you find how much space is in the container
length is 13
width is 15
height is 10
2 * (15 * 13 + 10 * 13 + 10 * 15)= 950
The total space in the container is 950
Then multiply it by 0.39 to find the weight
950 * 0.39 = 370.5
Round to the nearest pound
.5 rounded is rounded to a whole number
371 pounds
