Answer:
88 ft^2
Step-by-step explanation:
To find the surface area of a rectangular figure
SA = 2(lw+lh+hw)
where l=length, w= width, h = height
let l=6, h=2, w=4
= 2 (6*4+ 6*2+ 2*4)
=2 (24+12+8)
=2 (44)
= 88
SA = 88 ft^2
[ Answer ]
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
