Describe the relationship among the number of centimeter cubes you used to fill each layer, the number of layers, and the volume

of the prism
Mathematics

A centimeter cube is 1^2  (I don't have a font for that, the two should be higher and smaller)

the amount to fill a layer is the area, so height times area is the volume
L= length   W= width  V= Volume   A= Area   H= height

A= L · W
V= L · W · H or A <span>· H</span>

If Charlotte spent 25% more on furniture than she will on flooring, how much did she spend on furniture?
SashulF [63]

Answer:

Charlotte spent   x + 0.25x on furniture

Step-by-step explanation:

Given:

Charlotte spent 25% more on furniture than she will on flooring

To Find:

Amount spent on furniture = ?

Solution:

Let the amount spent on flooring be x

and the amount spent on furniture be y

25% more on furniture than she spent on flooring can be written as

=>25% of x

So the cost spent on furniture will be

=>y= cost spent on flooring +  25% of cost spent on flooring

=>y= x + 25% of x

=>y=x + \frac{25}{100} \times x

=> y=x + 0.25x
