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? 1 point

Answer 1

Answer:

here is ur ans

Explanation:

total surface are = 2lb+2bh+2hl = 2( 6+27+18) = 102

surface area of cube = 6(5)² = 150

so cube has greater surface area than cuboid

hope it help u

Answer 2

Answer:

TOTAL SURFACE AREA OF CUBOID

=2(lb+bh+lh)

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

=2*51

=102cm^2

TOTAL SURFACE AREA OF CUBE

=6a^2

=6*5*5

=150cm^2

∴cube>cuboid

=150>102
