88 Ft^2
[ Explanation ]
- Formula for area of a rectangular prism -
A = 2(w * l + h * l + h * w)
In other words:
Area = width times length + height times length + height times width * 2
- Width times length -
4 * 6 = 24
- Height times length -
2 * 6 = 12
- Height Times Width -
2 * 4 = 8
- Add -
24 + 12 + 8 = 44
- Multiple By 2 -
44 * 2 = 88
