Complete question :
A traditional "square" bale of hay is actually in the shape of a rectangular prism. Its dimensions are 2 feet by 2 feet by 4 feet. How many square bales contain the same amount of hay as one large "round" bale of height is 4 ft and its width is 5 ft?
Answer:
4 bales
Explanation:
Given :
Dimension of rectangular prism = 2 feet by 2 feet by 4 feet
Round Bale:
Height = 4 feets
Width = 5 feets
Volume of 'Square' Bale
Volume = 2 feets * 2 feets * 4 feets
Volume = 16ft³
Volume of 'round' Bale
V = πr²h
radius, r = 4/2 = 2 feet ;
V = π * 2^2 * 5
V = 62.831853 ft³
Volume of 'round' bale ÷ Volume of 'square' bale
62.831853 ft³ ÷ 16 ft³
= 3.9269908
= 4 (nearest whole number)
