Question

find the total surface area lateral surface area and length of the diagonal of a cuboid which is 5 metre long for 4 metre broad and 3 metre high

please answer me fast
And diagonal wala bhi aacha se solve karna​

Answer 1

Step-by-step explanation:

total surface area=96m²

lateral surface area=66m²

length of diagnol=√50

Answer 2

Given :-

• A cuboid which is 5 metre long for 4 metre broad and 3 metre high

To find :-

• Total surface area of cuboid
• Lateral surface area of cuboid
• Diagonal of cuboid

Solution :-

• Length of cuboid (l) = 5m

• Breadth of cuboid (b) = 4m

• Height of cuboid (h) = 3m

Total surface area of cuboid

→ 2(length × breadth + breadth × height + Length × height)

→ 2(lb + bh + lh)

→ 2(5 × 4 + 4 × 3 + 5 × 3)

→ 2(20 + 12 + 15)

→ 2(32 + 15)

→ 2 × 47

→ 94 m²

So, total surface area of cuboid is 94m²

Lateral surface area of cuboid

→ 2(length + breadth)height

→ 2(l + b)h

→ 2(5 + 4)3

→ 2 × 9 × 3

→ 18 × 3

→ 54 m²

Hence, lateral surface area of cuboid is 54 m²

Diagonal of cuboid

→ D = √l² + b² + h²

→ D = √(5)² + (4)² + (3)²

→ D = √25 + 16 + 9

→ D = √25 + 25

→ D = √50

→ D = 7.07m

Therefore,

• Total surface area of cuboid = 94 m²

• Lateral surface area of cuboid = 54 m²

• Diagonal of cuboid = 7.07 m
