Question

find the volume of total surface area and lateral surface area of cubic which is 15 M long 12 m wide and 4.5 M height

Answer 1

Hey friend!!

Here's ur answer...

__________________________

Length = 15 m.
Breadth = 12 m.
Height = 4.5 m.

Volume = L × B × H
= 15 × 12 × 4.5
= 810 m³.

Total surface area = 2 (LB + BH + HL)
= 2 ( (15 × 12) + ( 12 × 4.5) + ( 4.5 × 15)
= 2( 180 + 54 + 67.5)
= 2 ( 301.5)
= 603 m².

Lateral surface area = 2 (L + B) H
= 2 × ( 15 + 12) × 4.5
= 2 × 27 × 4.5
= 243 m².

Answer 2

hay!!
Dear user -

Here, L=15m b=12m h=4.5m

volume of the cuboid =(l×b×h)cubic units

=> (15×12×4.5)m²=810m³

Total surfaces of area of cuboid
=2(lb+bh+lh) sq units

=> 2(15×12+12×4.5+15×4.5)m²=603m².

Lateral surface area of the cuboid

[2(l+b)×h]sq units

[2(15+12)×4.5]m=243m²

I hope it's help you
