Question

lsa and tsa of a cuboid whose dimensions are length 5.5 m breadth 25cm height 75000mm​

Answer 1

Given

Length (l)=22cm

Breadth (b)=12cm

Height (h)=7.5cm

Lateral surface of the cuboid =2h(l+b)

⇒2×7.5(22+12)

⇒15(34)

⇒510cm2

∴ The lateral surface area of the cuboid is 510cm2.

So, the answer is B: 510cm2.

Answer 2

Answer:

Step-by-step explanation:

lsa=lateral surface area of cuboid=Lateral Surface area = 2 height(length + breadth) and 75000mm=7500cm 5.5m=550cm

2 x 7500(550 + 25)

=7500 x 575 x 2=8625000cm²

total surface area of cuboid=Total Surface area = 2 (Length x Breadth + breadth x height + Length x height)=2(550 x 25+550 x 7500)=4,12,63,75cm²
