Question

What are the possible expressions for the dimensions of the cuboid whose volume is 7x2 - 56x + 105 cubic units and value of x is greater than 5.

Answer 1

Answer:

Step-by-step explanation:

Volume of cuboid = 2x  

2

+10x+12=2(x  

2

+5x+6)

                              = 2(x  

2

+3x+2x+6)=2(x+3)(x+2)

∴ Length =2, breadth =x+3, height =x+2
