1.find the side of a cube whose surface area is 5400 square. cm?

30 cm

Step-by-step explanation:

Step 1: The surface area of  a cube = 6a^2, where "a" is the side of the cube.

Step 2: We are given surface area of a cube = 5400.

Step 3: Now plug in the surface area of the cube = 5400 and simplify.

5400 = 6a^2

a^2 = 5400/6

a^2 = 900

Now take square root on both sides, we get

a = √900

a= 30 cm

Therefore, the side of the cube is 30 cm.

Thank you.

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
