Question

find the total surface area of a cuboid whose length=3.5metres b=2.6metres and h=100metres​

Answer 1

Step-by-step explanation:

Given,

l=3.5 m, b=2.6 m, h= 100m

TSA of cuboid = 2(lb+bh+lh)

= 2(3.5×2.6+2.6×100+100×3.5)

=2(9.1+260+ 350)

=2×619.1

= 1,238.2

Answer 2

Given :

• Length of the cuboid = 3.5 m
• Breadth of the cuboid = 2.6 m
• Height of the cuboid = 100 m

To find :

• Total surface area of cuboid

Knowledge Required :-

→ Formula to calculate total surface area of cuboid :-

• TSA of cuboid = 2(lb + bh + hl)

where,

• l = length of the cuboid
• b = breadth of the cuboid
• h = height of the cuboid

Solution :

Total surface area of cuboid :-

→ TSA = 2(lb + bh + hl)

→ TSA = 2(3.5 × 2.6 + 2.6 × 100 + 100 × 3.5)

→ TSA = 2(9.1 + 260 + 350)

→ TSA = 2(619.1)

→ TSA = 1,238.2

Total surface area of cuboid = 1,238.2 m²

━━━━━━━━━━━━━━━━━

Know MorE :-

• Volume of cuboid =  length × breadth × height
• Perimeter of cuboid = 4 (length + breadth + height)
• Total surface area of cube = 6 × side²
• Volume of cube = side³
• Perimeter of cube = 12 × side
• Area of square = side × side
• Perimeter of square = 4 × side
• Diagonal of square = √2a
• Perimeter of reactangle = 2(l + b)
• Diagonal of rectangle = √l² + √b²
