Answer:
about 1036 pounds
Step-by-step explanation:
First we'll find the volume, then we'll use that to get the weight.
V = lwh
= 7.5 * 14 * 10.5
= 1102.5 cubic feet
We know that it weighs .94 pounds per cubic foot. The per tells us to multiply.
1102.5 cubic feet * .94 pound / cubic foot
= 1036.35 pounds
<u>= about 1036 pounds</u>

Answer:
339.24
Step-by-step explanation:
To find the surface area, you will need to the the area of the base of the cylinder. To do that, use the formula A=pi (r)^2
The radius is half the diameter do r=3
3.14(3)^2 should give you about 28.27.
This is the area of the top and bottom of the cylinder.
Now, do 28.27x10=282.7 to find the height surface area.
282.7+28.27+28.27=Surface area.
SA= about 339.24
