Im not sure but if I did this right you should get 89.1 but then yet again I am NOT sure so try to work it out
<span>(a) What is the capacity of the container?
Volume = length * width * height
V = 4ft * 2ft * 3ft
V = 24 ft</span>³
<span>
(b) How much material was used to make the container?
Surface area = sum of 6 faces of the prism
4 ft x 3 ft = 12 ft</span>² → 12 ft² x 2 = 24 ft²
<span>4 ft x 2 ft = 8 ft</span>² → 8 ft² x 2 = 16 ft²
<span>2 ft x 3 ft = 6 ft</span>² → 6 ft² x 2 = 12 ft²
<span>
Surface area = 24 ft</span>² + 16 ft² + 12 ft² = 52 ft²<span>
</span>
Alright, we just need to reverse some operations done unto 43. Subtract the 15 from her collection.
43 - 15 = 28.
Sold half? Times half.
28 * 2 = 56
Make sure it works:
56 - 28 = 28. 28 + 15 = 43.
She had 56 cards to start with.
