1. The base of the treasure chest is the bottom edge
Because most chests are rectangles, we can assume that the base is also a rectangle
This means that the perimeter would be 3+3+2+2, which is 10 ft

2.
To find the area of the chest’s base, you must multiply 3 by 2

3*2 is 6, so the answer is 6 feet squared

3.
I’m not completely sure what this question is asking, but I’ll do my best

It looks like it is asking if you can find the surface area by multiplying the base by one of the side lengths (again, not sure which one because it’s not labeled)

This wouldn’t work regardless of the side length, however, because base times height is equal to the volume of the chest and not the surface area

4. To do this, it would be easier to find how much sand can fit in the chest, and then do weight after you have that figure

There are 12 inches in a foot, so the measurements of how much sand can fit in the chest could be found by multiplying 12 by the side length
This would leave you with measurements of 36, 24 and 24
Volume is base * height, so first multiply the two base measurements (36 and 24)
This leaves you with 624
Multiply that by height (24) and you get 14,976 cubic inches of sand

Because each cubic inch of sand weighs about 1 ounce, we know that the weight of the sand is 14,976 ounces

To find out how much that is in pounds, divide 14,976 by 16

This leaves you with 936 lbs
Add the additional 20 that comes from the chest and you get 956 lbs total
The chest weighs 956 pounds when filled with sand

Hope that helped!
