The length of a room is 4 metres longer than its width. The height of the room
is 3 metres and its volume is 1000m^3. Find the length and width of the room.
The formula for the volume of a rectangular solid is:
Height (h)=3 m
Volume (V)=1000 m^3
This is in standard form:
a=3, b=12, and c=-1000
Use the quadratic formula:
We can ignore the negative value, beacuse this is a dimension.
x is approximately 16.36663642
The Width (W): x=16.3666 m round off to whatever your teacher asks for.
The length (L): x+4=16.3666+4=20.3666 m
