Question

Answer this question from volume and surface area lesson​

Answer 1

heightof cuboid =1.5×6 cm.

= 9cm.

breadth of cuboid =1.5 cm.

length of cuboid =1.5 cm.

Hence,

total surface area of

cuboid =2(lb+bh+hl)

=2(1.5*1.5 + 1.5*9 + 9*1.5)

=2(2.25 + 13.5 + 13.5)

=2(29.25)

= 58.5 square cm.

lateral surface area of

cuboid = 2×h( l+b)

=2× 9(1.5+1.5)

=18(3)

= 54 square cm.

volume of cuboid = l*b*h

=1.5 * 1.5 * 9 cubic cm.

= 20.25 cubic cm.
