Ineed with these 3 problems plz explain! : )

14.
4(5.6) = 4(6.0 - 0.4) = 4(6.0) - 4(0.4) = 22.4

16.
4(6 + 7) = 4(6) + 4(7) = 52

18.
14(10 - 5) = 14(10) - 14(5) = 70

Given:

Stacked Hay Bales:

L = 1 1/3 feet
W = 4 feet

The volume of each hay bale is equal to 10 2/3 cubic feet
The number of hay bales stacked = 8

To solve for the height, use the volume of the bales and the given length and width of a single bale.

V = l x w x h
10 2/3 cubic feet = 1 1/3 feet * 4 feet * height
height = 2 feet

So, if the height of one bale is 2 feet, then the height of 8 bales stacked is

2 feet * 8 bales = 16 feet

Therefore the height of the stacked hay bales is 16 feet.
