Answer 2

Step-by-step explanation:

volume of cuboid is lbh

ratio is 3:4:6

so let l=3x

b=4x

h=6x

volume is 576cm³

lbh=576

(3x)(4x)(6x)=576

72x³=576

x³=8

x =2

so length is 6

breadth is 8

height is 12

surface area of cuboid is

2(lb+bh+hl)

2[(6)(8)+(8)(12)+(12)(6)]

2[48+96+72]

2[216]

432cm²
