plzz help me fast​

Answer 1

Answer: 840 sqcm

Step-by-step explanation:

Given,

Length = 20cm

Breadth = 8 cm

Height = 15cm

Formula for Lateral Surface area of Cuboid : 2h(l+B)

2*15(20+8)

30(28)

840 sqcm. Here is your answer..

Answer 2

Answer :-

840 sq. cm.

Explanation :-

Given :

• Length of Cuboid = 20cm.
• Breadth of Cuboid = 8cm.
• Height of Cuboid = 15cm.

To Find :

• Lateral Surface Area.

Solution :

Formula Used :-

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

Substitute the Values.

⇒ L.S.A = 2(20 + 8)15.

⇒ L.S.A = (2)(28)(15).

⇒ L.S.A = 56 × 15.

⇒ L.S.A = 840 sq. cm

Extra Shots :-

• T.S.A of Cuboid = 2(lb + bh + hl).
• T.S.A of Cube = 6s²
• L.S.A of Cube = 4s²
• Volume of Cuboid = l × b × h.
