 Question 57024This question is from textbook Oxford mathematics for the Caribbean : The length of a room is 4 metres longer than its width. The height of the room is 3 metres and its volume is 1000m3. Find the length and width of the room. This question is from textbook Oxford mathematics for the Caribbean Answer by funmath(2925)   (Show Source): You can put this solution on YOUR website!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 Width (W)=x Length (L)=(x+4) 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 Happy Calculating!!!
