let us take
length = 5x
breadth = 3x
height = 2x
CSA = 2( BH + lh )
288 = 2 ( 6x^2 + 10x^2)
32x^2 = 288
x^2 = 9
x = 3
length = 5 × 3 = 15cm
breadth = 3 × 3 = 9cm
height = 2 × 3 = 6cm
length = 5x
breadth = 3x
height = 2x
CSA = 2( BH + lh )
288 = 2 ( 6x^2 + 10x^2)
32x^2 = 288
x^2 = 9
x = 3
length = 5 × 3 = 15cm
breadth = 3 × 3 = 9cm
height = 2 × 3 = 6cm
