First rectangle:
Has 3 cubes in each 5 layers, and imagine it, so we have all dimension needed which is:

V=15 cubic inches.

Doing the same like that to get:
l=5 unit
w=1 unit
h=3 unit
V=15 cubic inches. As a result, there are no prism that are greater to each other, which mean that they have the same volume of 15 cubic inches. Hope it help!

A bicycle has a listed price of $625.99 before tax. If the sales tax rate is 7.5%, find the total cost of the bicycle with sales
Serhud [2]
With tax, it would be 107.5% of 625.99. 107.5% is 1.075 in decimal form so you do 1.075(625.99). That gives the rounded answer of $672.94. :)
