Answer:
17.8 square feet of wood are needed to build a cabinet
Step-by-step 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
[tex] = 2(lb + bh + hl)[/tex]
[tex] = 2 \times (2.3) (1.4) + (1.4) (1.4) + (1.4) \times (2.3)[/tex]
[tex] = 2 \times (3.22 + 1.96 + 3.72) \\ = 2 \times 8.90 \\ = 17.8ft {}^{2} [/tex]
Thus, 17.8 square feet of wood are needed to build a cabinet
