Question

find the total surface of area of cuboid of length 15 cm,breadth 10 cm and height 5 cm solve​

Answer 1

Answer:

• The total surface of area of cuboid is 550 cm².

Step-by-step explanation:

Given that:

Dimensions of the cuboid.

• Length = 15 cm
• Breadth = 10 cm
• Height = 5 cm

To Find:

• The total surface of area of cuboid.

Formula used:

• T.S.A. = 2[(LB) + (BH) + (HL)]

Where,

• T.S.A. = Total surface of area of cuboid
• L = Length of cuboid
• B = Breadth of cuboid
• H = Height of cuboid

Finding the total surface of area of cuboid:

⟶ T.S.A. = 2[(15 × 10) + (10 × 5) + (5 × 15)]

⟶ T.S.A. = 2[150 + 50 + 75]

⟶ T.S.A. = 2[275]

⟶ T.S.A. = 550

∴ The total surface of area of cuboid = 550 cm²

Answer 2

EXPLANATION:-

length(l)=15 cm

breadth(b)=10 cm

height(h)=5 cm

Total surface area(T.S.A)=?

TSA OF CUBOID=  2[(lbB) + (bhH) + (hl)]

==>T.S.A. = 2[(15 × 10) + (10 × 5) + (5 × 15)]

==>T.S.A. = 2[150 + 50 + 75]

==> T.S.A. = 2[275]

==> T.S.A. = 550

So TSA is 550 cm²

EXTRA INFORMATION:-

TSA OF CUBE =   6a²    (a=side of cube)

TSA of cylinder= 2$\pi$r(h+r)  (h=height, r=radius)
