Question

The total surface area of the given cuboid equals 292 m2.



If its length and breadth equal 8 m and 6 m respectively, what is its height?

Answer 1

Answer: Height = 7 m

Step-by-step explanation:

Total Surface Area of cuboid = 2(lb+bh+hl)

                                         292 = 2 (8×6 + 6×h + h×8 )

                                         292 = 2 (48+6h+8h)

                                         292 = 96 + 28h

                                          28h = 196

                                           h = 7 m
