Question

Tsa of cuboid is148cm its length is4cm and breadth5cm find its height

Answer 1

Answer:

Height = 6 cm

Step-by-step explanation:

TSA = 2*(AB+BC+CA)

=>148 = 2 * (4*5 + 4*C + 5 *C)

=> 74 = 20 + 9C

=> 54 = 9C

=> C = 6

Answer 2

Answer:

6 cm

Step-by-step explanation:

Let the height be x cm

Length = 4 cm

Breadth = 5cm

therefore,

TSA = 2(lb + bh + lh) cm^2

= 2 × (20 + 5x + 4x) cm^2

= 40 + 18x cm^2

By the problem,

40 + 18x = 148

18x = 148 - 40

x = 108/18

x = 6
