Question

find the lateral surface of area , total area of coboid whose lenghth is 5cm , breath is 3cm and hight is 6cm ...
solve with solution​

Answer 1

Step-by-step explanation:

lateral surface area= 2(l+b)+h

2(5+3)×6

=96 cm²

Answer 2

Answer :-

• L.S.A. of Cuboid = 96 sq. cm.

• T.S.A. of Cuboid = 126 sq. cm.

Explanation :-

Given :

• Length of Cuboid = 5 cm.
• Breadth of Cuboid = 3 cm.
• Height of Cuboid = 6 cm.

To Find :

• Lateral and Surface Area of Cuboid.

Solution :

(i) L.S.A. of Cuboid = 96 sq. cm.

We know that,

L.S.A. of Cuboid = 2(l + b)h.

Put the values.

➠ L.S.A. of Cuboid = 2(5 + 3)6.

➠ L.S.A. of Cuboid = (2)(8)(6).

➠ L.S.A. of Cuboid = 16 × 6.

➠ L.S.A. of Cuboid = 96 sq. cm.

(i) T.S.A. of Cuboid = 126 sq. cm.

We know that,

T.S.A. of Cuboid = 2(lb + bh + hl).

Put the values.

➠ T.S.A. of Cuboid = 2{(5)(3) + (3)(6) + (6)(5)}

➠ T.S.A. of Cuboid = 2(15 + 18 + 30).

➠ T.S.A. of Cuboid = 2(63).

➠ T.S.A. of Cuboid = 126 sq. cm.
