Answer:

Meters, Squared meters or cubic meters

Explanation:

Here we want to give measurements for a house.

We can give 3 types of measures:

– We can give the length of the house. This is a one-dimensional size; length is measured in meters (m), so this measure is given in meters.

– We can give the measure of the area of the whole floor of the house: the area is defined as

$A=L_1\cdot L_2$

where $L_1,L_2$ are the lengths of the two sides. Since each length is measured in meters, the area is measured in

$[A]=[m]\cdot [m]=[m^2]$

So, squared meters.

– We can give the measure of the volume of the whole house: the volume is defined as

$V=L_1\cdot L_2 \cdot L_3$

where $L_1,L_2,L_3$ are the lengths of the 3 sides. Since each length is measured in meters, the volume is measured in:

$[V]=[m][m][m]=[m^3]$

Therefore, cubic meters.
