Question

The volume of a cuboid is twice the volume of a cube. If the dimension of cuboid are 9cm, 8cm, 6 cm, what is the total surface area of cube.​

Answer 1

Step-by-step explanation:

volume of cuboid =l x b x h

=9*8*6

=320cm

total surface area =2lw+2lh+2hw

l=lenght

w=width

h= height

then put the value in this formula

Answer 2

Answer:

Step-by-step explanation:

Let the volume of cube = x

According to Q, the volume of cuboid =2x

So, volume of cuboid = l*b*h

                                    =9*8*6= 432cm sq.

therefore, volume of cuboid = 1/2*432= 216sq. cm

   (side of cube)^3  = volume of cuboid

    side of cube       =  216^1/3

                                = 6cm

T.S.A of cube = 6*side^2

                      = 6* 6^2

                      =216cm^2
