Answer:
6 ft^2
Step-by-step explanation:
If the object in question is a cube, then we could say the length is 1, the depth is 1 and the height is 1, in which case each side of the cube has an area of 1 ft^2.
There are 6 such sides, so the total surface area is 6 ft^2.
Next time please be explicit in naming the shape, either verbally or with a diagram.
A (1)= -5×3(1)-1
a(1)= -5×3-1
a (1)= -16
A(4)= -5×3(4)-1
a (4)= -5×12-1
a( 4) = -60-1
a(4)= -61
A(8)= -5×3(8)-1
a(8)= -5×24-1
a(8)= -120-1
a(8)= -121
