Question

plz give me answer..​

Answer 1

Answer:

8cm

Step-by-step explanation:

Given: In Cuboid,

Length = 12cm

Breadth = 6cm

Total surface area = 432cm²

Solution:

Let the height be h.

A/Q,

Total surface area of Cuboid = 2( lb+bh+lh)

=> 432 = 2 ( 12×6 + 6×h + 12×h)

=> 432 = 2 ( 72 + 6h + 12h)

=> 432 = 2( 72 + 18h)

=> 432/2 = 72 + 18h

=> 18h = 216 - 72

=> 18h = 144

h = 8 cm

Therefore, height = 8 cm. ANS.

Answer 2

Given :

Volume of the cuboid = 432cm²

Length of cuboid = 12cm

Breadth of cuboid = 6cm

To find :

Height of cuboid

Solution :

Formula for finding height with given volume, length and breadth

$v \div (l) \times (b)$

Length × Breadth

12 × 6 = 72

Volume of cuboid divided by length and breadth

432÷72

= 6

Final Answer

The height of the cuboid as summarised is 6cm
