Question

How many square feet of wood are needed to build a cabinet that is 2 feet 3 inches tall, 1 foot 4 inches deep, and 1 foot 4 inches wide? (Assume that wood is needed for all six surfaces. )

Answer 1

17.8 square feet of wood are needed to build a cabinet

Explanation:

For Cuboid:

l = 2 feet 3 inches = 2.3 ft

b = 1 foot 4 inches = 1.4 ft

h = 1 foot 4 inches = 1.4 ft

TSA OF CUBOID

`= 2(lb + bh + hl)`

`= 2 * (2.3) (1.4) + (1.4) (1.4) + (1.4) * (2.3)`

`= 2 * (3.22 + 1.96 + 3.72) \\ = 2 * 8.90 \\ = 17.8ft {}^(2)`

Thus, 17.8 square feet of wood are needed to build a cabinet
