Answer:
the answer is 73.5
Step-by-step explanation:
to find the are of the box you have to do the mathematical equation of LxWxH (lengthxwidthxheight) in this case L=6, W=3.5, and H=3.5 so your equation would be 6x3.5x3.5 = 73.5
(2 × 1/2 × 20 × 15) + (16 ×15) + (20 × 16) + (25×16)
300 + 240 + 320 + 400 = 1260 ft²
733.05
