plz answer me fast​

Answer 1

Answer:

Volume of the rectangular solid=192cm^3

Step-by-step explanation:

let the length, breadth, height be 2x, 3x, and 4x respectively.

Total Surface Area

= 2(Lb+Lh+bh) =208

=> Lb+Lh+bh = 104

=> 2x × 3x+2x ×4x+3x × 4x=104

=> 26x^2 = 104

=> x=2

L = 4cm

b = 6cm

h = 8cm

Volume = Lbh= 196 cm^3
