Answer 1

Question:

3 cubes of each edge of 6 cm are joined end to end . Find the surface area of the resulting cuboid.

Answer:

The surface area of the resulting cuboid is 504 cm².

Given:

3 cubes of each edge of 6 cm are joined end to end .

To find:

Find the surface area of the resulting cuboid.

Explanation:

3 cubes of each edge of 6 cm are joined end to end.

∴ For the resultant cuboid we get_

Length(l) = (6+6+6) cm

             = 18 cm.

Breadth(b) = 6 cm.

Height(h) = 6 cm.

We know that,

Surface area = 2(lb+bh+hl)

                     = 2×  (18×6+6×6+6×18)

                    = 2×(108+36+108)

                     = 2 × 252

                    = 504 cm²

∴ The surface area of the resulting cuboid is 504 cm².
