Answer:
1a) 3203.125
1b) 1137.5
2a) 8
Step-by-step explanation:
1a)
rectangular prism = cuboid = 4 rectangles and 2 squares
how much water it can hold = volume of cuboid (length x width x height)
length = 20.25
width = 12.5 (because all sides of a square is the same)
height= 12.5
20.5 x 12.5 x 12.5 = 3203.125(what ever unit you use)
1b) how much wrapping paper = surface area = the sum of the area of each side
4 rectangles = 4(20.5 x 12.5) 1025
2 squares = 2(12.5 x 12.5) 312.5
1025 + 312.5 = 1137.5 (preferred unit ^ 2)
