Mean is 151 because you add all numbers and divide by how many numbers their is
Expression step by step:
(4 + 56 + 66) - 4 = → we solve for 4 + 56
(60 + 66) - 4 = → we solve for 60 + 66
126 - 4 = → we solve for 126 - 4
122 → final answer

Answer:294
Step-by-step explanation: you’re trying to find the surface area of the cube to find out how much material Daria needs. To do so find the area of 1 face of the cube (which is a square). The problem gives us 1 side of the square as 7cm. A square has the same length for its 4 sides, so to find the area of that 1 face do 7 x 7=49. The question also gives the hint that a cube has 6 faces so you would multiply the 49 by 6 to get the total surface area of the cube. 49 x 6=294.
Not sure if this is right but hope it helps.
