Answer:

Step-by-step explanation:
The perimeter is the sum of the side lengths of the shape. Since a square has equal side lengths, each side must be the same. Divide 52/4=13cm. 13cm is the length of 1 side. Area is length times width, and since each side is 13, multiply 13cm*13cm to get the area, which is

Answer:
Step-by-step explanation:
10/7 x 9/8 = 90/56 = 45/28.

Answer:
Prism volume = lbh
= 10*8*12
= 960cm^3

Hole volume = lbh
= 2*3*12
= 72cm^3
Final volume = 960 - 72 = 888cm^3
