Answer:

CE = 6

then

2×CE = 12

You plan to construct a brick wall measuring 14.5 ft. in length, 5.5 ft. high, and 0.5 ft. in width. If a brick measures 6 in. x

Kobotan [32]

14.5 x 5.5x 0.5 = 39.875 cubic feet for the wall

brick = .5 x .333 x 0.167 = 0.0278 cubic feet rounded to 0.03

39.875/0.03 = 1329.16

so approximately 1330 bricks are required.

This could be a little different depending on how you round everything off
