A rectangular sandbox will be constructed for the students at an elementary school. The sandbox will be filled to the top of the sandbox with sand.
If each bag of sand contains 2.6 cubic feet of sand, how many bags of sand will need to be
purchased to completely fill the sandbox?

i’m here for points.

b, 20 yards

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
