•when columns are intentionally designed to swell at the midpoint, this is called

Entasis

Explanation:

Entasis is a slight thickening in the central part of the shaft of a column in order to correct the optical illusion that the rectilinear sides give, of an inward curve.

The architrave of the jonic order is composed of three strips, each slightly more prominent than the lower one. The frieze is continuous around the entire temple and is usually ornamented with sculptural decoration. On the facade, the columns are more slender than the Doric ones, have a much smaller entasis, and are placed at a greater distance from each other.

35 cubic if the woodchuck was digging his burrow.

perimeter = 2l +2w, divide total perimeter by 2 for total length of 1 side and 1 width

172/2 = 86 (  total for 1 side and 1 width)

86-24 = 62 (since length is 24 ft longer subtract 24 then divide by 2 for width)

62/2 = 31

width = 31 feet

length = 31 +24 = 55 feet

check: 31*2 = 62, 55*2 = 110,  110+62 = 172
