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:
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
