cube
V=L^3
if it is doubled, then each dimention (LWH) is dobubled
since L=W=H
V=(2L)^3
V=8L^3
compared to orignal
L^3 vs 8L^3 it is 8 times more
demonstarte
10^3=1000
5^3=125
1000/125=8, not 2

36 square pieces of cake can be cut from the rectangular cake.
What is rectangle?
"A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles."
What is square?
"A square is a shape that has four straight sides of the same length and four angles of 90 degrees"
It is given that the cake is a rectangle and squares are cut from it.
To find the area of the cake:
Area = 22.5 × 10
= 225
The area of each square piece cut from the cake:
Area = 2.5²
=6.25
To find the number of pieces cut, divide the area of the cake by the area of each piece.

Answer:
In order to find MAD follow the following steps
Step-by-step explanation:
The following rules may be followed to find MAD
- Start by finding the mean of the data set.
- Find the sum of the data values, and then divide the sum by the number of data values.
- After that find the absolute value of the difference between each data value and the mean.
- Calculate the sum of the absolute values of the differences.
- Finally divide the sum of the absolute values of the differences by the number of data values.
Answer:
A measure used to find how much the values in a data set vary from their mean is called as the mean absolute deviation. It is also termed as mean deviation or average absolute deviation. It can be calculated by finding the mean of the values first and then find the difference between each value and the mean
