Question

find the volume the lateral surface area and the total surface area of the cuboid whoes dimension are length 12cm breadth 8cm height 4.5cm​

Answer 1

Length = 12 cm

Breath = 8 cm

Height = 4.5 cm

The volume of the cuboid is Length × Breadth × Height = 12 × 8 × 4.5

= 432 cm^³

The Total surface area of the cuboid is 2(l+b) h

= 2 ( 12+ 8) × 4.5

= 2× 20 × 4.5

= 18 cm

Answer 2

Answer:

Step-by-step explanation:

volume of cuboid=12*8*4.5=432

lateral surface area=2(l+b)*h=2(20)*4.5=40*4.5=130

total surface area=2(lb+bh+hl)=2(96+36+54)=186*2=372
