Question

Find the lateral surface are and the total surface area of the cuboid whose dimemsions are l=12cm b=8cm h=4.5

Answer 1

Answer:

lateral surface area of cuboid= 2h(l+b)

total surface area of cuboid =2(lb+BH+hl)

Step-by-step explanation:

lateral surface area= 2h(l+ b)

=2×4.5(12+8)

=9×20

=180cm2

total surface area=2(lb+bh+hl)

=2(96+36+54)

=2(186)

=372cm2
