b.
Step-by-step explanation:
<span>B: To make the box, we need 2 triangular ends,
and 3 rectangular sides. Side the volume = 3240
and the height = 30, the area of each base (end) = 108.
The sides have areas of 30 x 42 = 720, and 30 x 15 = 450,
and there are 2 of those. So total area = 108 + 108 + 720 + 900 = 1836 cm^2
