Question

QNO13.If length, breadth and height of a cuboid is 5 cm, 3 cm and 4cm .Then its total surface area will be
94 cm2
49 cm2
98 cm 2
None of these​

Answer 1

Answer:

94cm²

Step-by-step explanation:

hope it helps

total surface area of a cuboid = 2(lb + bh + hl)

= 2( 5*3 + 3*4 + 4*5 )

= 2( 15 + 12 + 20 )

= 2( 47 )

= 94cm².

Answer 2

Answer :-

Option [A] 94 cm²

Explanation :-

Given :

• Length of Cuboid = 5 cm.
• Breadth of Cuboid = 3 cm.
• Height of Cuboid = 4 cm.

To Find :

• Total Surface Area of cuboid.

Solution :

We are given the dimensions and have to find T.S.A. of Cuboid.

Formula :- 2(lb + bh + hl).

➝ T.S.A. = 2[(5 × 3) + (3 × 4) + (5 × 4)]

➝ T.S.A. = 2[15 + 12 + 20]

➝ T.S.A. = 2[27 + 20]

➝ T.S.A. = 2[47]

➝ T.S.A. = 94 cm²

Therefore, T.S.A. = 94 sq. cm.
