Answer 2

Given:

Kaley connects 20 1-foot wooden cubes in a row.

To find:

The surface covered with fabric on the long bench

Solution:

Length of the long bench (l) = 20feet

Height of the long bench (h) = 1 foot

Width of the long bench (b) = 1 foot

Total Surface area of a cuboid = 2(lb + bh + hl)

                                                   = 2( 20 + 1 + 20)

                                                   = 2 (41)

                                                   = 82 ft²  

Hence, the surface covered with fabric on the long bench is  82 ft².
