Answer:
it's 1
Step-by-step explanation:
when one is multiplied by three times.it gives us three and its difference result negative five 3–8 = -5
The algebraic expression would be 4 - n, I believe.
1. To find the length of the edge, you will divide the total distance of 36 cm between the 4 edges that are shown.
36/4 = 9 cm per edge.
2. To find the surface area, find the area of one square (9 cm x 9 cm = 81 square cm), and multiply it by 6.
81 square cm x 6 = 486 square cm
486 square cm is the surface area.
