Question

the lateral surface area and total surface area of a cuboid are 238cm2 and 382cm2.if the height of the cuboid is 7cm,find the volume of cuboid​

Answer 1

Answer:

448

Step-by-step explanation:

Lateral surface area of a cuboid is 224cm

2

Height (h)=7cm

(i) 2(l+b)×h=224

⇒ 2(l+b)×7=224

⇒l+b=

14

224

=16 cm

But l=b(Since the base of cuboid is a square)

So, 2×side=16 cm

⇒ side =

2

16

=8 cm

(ii) Volume of cuboid =lbh=8×8×7 cm
