Answer 1

Answer:

height = 30 cm. Work: Read the previous  

sentence, where it says the length (= height)  

of the box is 30 cm.  

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
