Answer:
5. Feet^3 or feet cubed
6. Feet^2 or feet squared
Explanation:
5.
This is asking for the volume of this cube and the formula for that is length * width * height or l*w*h.
In any case if it doesn't have the length or width or height of the cube it would be logical to just say feet^3 or feet cubed, but if you do find one of the lengths then just multiply it by itself by 3 times for example 3*3*3.
6.
This question is asking for the surface area of the figure and that formula would be 2(wl+hl+hw), w stands for witdh l stands for length and h stands for height.
Since it doesn’t have the units listed the logical answer would be feet^2 or feet square but if you do find it just plug the numbers into the formula I gave you.
