Question

Find out the answer of the question asked below.
If A= 1300cm², b=10cm, h=15cm then find length.
Please show full process.

Answer 1

Answer:

8.666

Step-by-step explanation:

area = length×breadth×height

1300= l×10×15

l= 1300/150 = 8.666 ( approx 8.67)

Answer 2

Answer:

$\large\sf\red{L = 20 \: cm}$

Explanation:

Total Surface Area( TSA ) = 1300 cm²

Breadth ( B ) = 10 cm

Height ( H ) = 15 cm

Let Length = L

We know that, TSA = 2( LB + BH + HL )

Put all the given values in the above mentioned formula

1300 = 2[ L(10) + (10)(15) + (15)L ]

1300 = 2 ( 10L + 150 + 15L )

1300 = 2( 25L + 150 )

1300 = 50L + 300

1300 - 300 = 50L

1000 = 50L

50L = 1000

$L = \frac{1000}{50} cm$

$L = \frac{100}{5} cm$

$\huge\mathbb\purple{L = 20 \: cm}$

Hope it helps you!
