The length, breadth and height of a cuboid are consecutive integers. If the volume is 336 cubic units, what is the total surface area?
Elementary MathematicsMensuration
- A288 square units
- B292 square units
- C296 square units
- DCannot be determined
Explanation
n(n+1)(n+2)=336=6*7*8, so the sides are 6,7,8. Total surface area=2(42+56+48)=292. Factoring 336 by trying consecutive triples near cubert(336)~7 is the way in.
