Answer 1

Answer: $8966.44\ \text{square units}$

Step-by-step explanation:

Given

The dimension of the chair is

$\text{Width w= }49\ \text{units}\\\\\text{Length l= }28.7\ \text{units}\\\\\text{height h= }39.6\ \text{units}$

Suppose, the chair is in a rectangular shape, its Surface area is given by

$\Rightarrow SA=2[lw+wh+lh]\\\\\text{Insert the values}\\\\\Rightarrow SA=2[49\times 28.7+28.7\times 39.6+39.6\times 49]\\\\\Rightarrow SA=2[1406.3+1136.52+1940.4]\\\Rightarrow SA=2\times 4483.22\\\Rightarrow SA=8966.44\ \text{square units}$
