Question

Which has greater total surface area,a cuboid of L = 2 cm , B = 3 cm H = 9 cm and cube of an edge is 5 cm?

Answer 1

Answer:

Total surface area of cuboid: 2(lb+bh+hl)

=2(2*3+3*9+9*2)

=2*51

=102

Total surface are of cube:

$6 a}^{2}$

$6 \times {5}^{2}$

6*25

=150

Cube has greater total surface area.
