A sheet of standard-size copy paper measures 8.5 in. by 11 in. If the ream (500 sheets) of this paper has a volume of 187 in.^3, how thick is the ream?

Question

 please help me :(

Answer 1

Thickness of the ream

187 = (8.5)(11)(h)

187 = 93.5h

2 = h

The ream is 2in thick.

 

Answer 2

The volume of the ream is length times width times height

V = LWH

 

L = 11

W = 8.5

H = ??

 

(11)(8.5)H = 187

 

H = 187/[(11)(8.5)]

H = 2 inches
