Answer:

24 cent

Step-by-step explanation:

If 13 inches of wire cost 39 cent.

We have to calculate how much 1 inch of wire would cost first, before determining the cost of 8 inches of wire.

If 13 inches of wire costs 39cents, Then 1 inch of wire would cost 3 cent.

That is 39/13, which gives 3.

If 1 inch of wire cost 3 cents. Two inches of wire would cost 6 cents we 3 inches of wire costs 9 cents.

To get the cost of 8 inches of wire, we therefore multiply 8 by 3, which gives 24.

8 inches of wire costs 24 cents.

A rectangular prism has a length of 1/1/4 yards, a width of 2/1/2 yards, and a height of 4 yards. Enter the volume of the prism
dmitriy555 [2]
Prism volume = lbh

= 10*8*12

= 960cm^3

Note: I'm assuming the hole was cut right through it...

Hole volume = lbh

= 2*3*12

= 72cm^3

Final volume = 960 - 72 = 888cm^3
