let length breadth and height of a solid is 3x 2x 1x
then 3x+2x+1x= 48
6x= 48

x = 8
3x=8×3=24
2x= 8×2=16
1x= 8×1=8

surface area 2(lb +bh +lh)
2(24×16+16×8+ 8×24)
2(416+128+192)
2×736
1442cm ..

pleas mark as brainleast..

Answer:

88 unit²

Step-by-step explanation :

l = 3x ; b = 2x ; h = 1x

volume = lbh = 3x × 2x × 1 x = 48

6x³ = 48 ; x³ = 8; x = ∛8 = 2 ;

therefore, x = 2

l = 2 × 3 = 6 unit

b = 2 × 2 = 4 unit

h = 2 × 1 = 2 unit

TSA = 2(lb + lh + bh)

2 ( 24 + 8 + 12)

2 ( 44) = 88 unit²


sadaf270: i think this answer is correct
anandrajraj: your wrong thoooo
NishadAnjali: sadaf answer is correct
sadaf270: yes this is correct 88cm2
sadaf270: when we take x=2
