Question

the ratio
of length ,breadth and height of a solid cuboid is 4:3:2 and the area of a whole surface is 468 sq.cm. Find its volume​

Answer 1

Answer:

648cm^3

Step-by-step explanation:

Area of cuboid=2(lb+lh+bh)

468=2(4x*3x+4x*2x+3x*2x)

234=12x^2+8x^2+6x^2

234=26x^2

234/26=x^2

9=x^2

x=3

now,

length=4*3=12cm

breadth=3*3=9cm

height=2*3=6cm

now,

Volume=l*b*h

=12cm*9cm*6cm

=648cm^3
