Step-by-step explanation:

It is given that length =15 m, breadth 6 m and height =5 cm=0.5 m

We know that

Volume of cuboid =1×b×h

By substituting the value we get

Volume of cuboid =15×6×0.5

By multiplication

Volume of cuboid =45 m

3

We know that

Lateral surface of a cuboid =2(1+b)×h

By substituting the values

Lateral surface area of a cuboid =2(15+6)×0.5

On further calculation

Lateral surface area of a cuboid =2×21×0.5

By multiplication

Lateral surface area of a cuboid =21 cm

2

We know that

Total surface area of cuboid =2(Ib+bh+Ih)

By substituting the value

Total surface area of cuboid =2(15×6+6×0.5+15×0.5)

On further calculation

Total surface area of cuboid =2(90+3+7.5)

So we get

Total surface area of cuboid =2×100.5

By multiplication

Total surface area of cuboid =201 m

Answer:

It is given that length = 15 m, breadth 6 m

and height = 5 cm = 0.5 m

We know that

Volume of cuboid = 1 xbxh

By substituting the value we get

Volume of cuboid-15×6×0.5

By multiplication

Volume of cuboid 45 m²

We know that

Lateral surface of a cuboid=2(1+b) x h

By substituting the values

Lateral surface area of a cuboid=2(15+

6) x 0.5

On further calculation

Lateral surface area of a cuboid = 2 x

21 x 0.5

By multiplication

Lateral surface area of a cuboid = 21 cm²

We know that

Total surface area of cuboid=2(1b + bh+Ih)

By substituting the value

Total surface area of cuboid=2(15 x 6+ 6 x 0.5 + 15 x 0.5)

On further calculation

Total surface area of cuboid 2(90+3+

7.5)

So we get

Total surface area of cuboid = 2 × 100.5

By multiplication

Total surface area of cuboid - 201 m²
