The face of one side of a cube is a square shape. The formula for the area of a square
A=s² where s=side length
plug in the data we know
64cm²=s²
√64cm²=s
8cm=s
The side length on the cube is 8cm
The formula for the volume of a cube is
V=s³ where s=side length
plug in the data that we know
V=8³
V=512cm³
Answer:
1,200
Step-by-step explanation:
So first we need to find the perimeter

so it costs 10 per meter
Answer:
-11
Step-by-step explanation:
X + 8 = -3
x = -11
11-8
3
-11 - 8 = -3
Answer:B
Step-by-step explanation:if it's a negative 3/4x then in be there is a -4 and there is a -7 so we can do -7 -4 but 4 is a negative so it turns into a positive so it's _
-7+4 and it become a smaller negative so -7+4 = -3. So it has to be B. Hope this gets brainliest
