1.) To find the surface area, we want to find the area of each side, then add them all up together:
Area of base=lwA=(5)(5)A=25 cm²
Area of triangle=1/2bhA=(1/2)(5)(12.5)A=31.25 cm²
Since the 4 triangles have the same area, we can multiply the area we found by 4 and then add the area of the square:
SA=(4)(31.25) + 25SA=125+25SA=150 cm²
2.) <span>To find the volume use the formula:
V=(1/3)lwh
V=(1/3)(5)(5)(12.5)
V=104.167 cm^3</span>
Answer:12cm
Step-by-step explanation:3+3+3+3 because its 3x3 so their is 3cm on each side
To find the average you would add the three numbers together 169.74+235.95+219.21
to get a total of $624.90 divide that number by 3 to get the average which is $208.30 as the average sale per day
It is 5 because you have to do 12 squared minus 13 squared and then square root that which equals 5
The answer to this equation is 45
