A cube has volume 216cm find total surface area of cube​
Katena32 [7]

Answer:

Answer: 216 cm2 (square centimetres cm^{2}, in your question you had to put cm3, cubic centimetres, it's IMPORTANT )

Step-by-step explanation:

A perfect cube by definition has 3 equal dimensions, as an immediate rule: volume and total surface are equal, only the unit of measure changes (cubic for the volume, square for surface).

But let's calculate it anyway:

Volume  = Edge * Edge * Edge = length * width * depth = Edge^{3}  (remember: all edges are equal in this case)

so Edge = \sqrt[3]{Volume}

in your example Edge = \sqrt[3]{216} = 6cm

So the surface of one side is 6*6 = 36cm^{2}

There are 6 sides in total, so the total surface is 6*36 = 216 cm^{2}

Note: I call them "edges" but in case of a cube most say just "length"

Is this relation a function? explain
Anton [14]

Answer:

A function is a relation in which no two ordered pairs have the same first element. A function associates each element in its domain with one and only one element in its range. Solution: a) A = {(1, 2), (2, 3), (3, 4), (4, 5)} is a function because all the first elements are different.

Solve The Following Expression..<br><br>#No Spam..​​
Rainbow [258]

\\ \sf\longmapsto \dfrac{x+0.25}{3}-0.5=x

\\ \sf\longmapsto \dfrac{x+0.25-1.5}{3}=x

\\ \sf\longmapsto x-1.25=3x

\\ \sf\longmapsto x-3x=1.25

\\ \sf\longmapsto -2x=1.25

\\ \sf\longmapsto x=\dfrac{1.25}{-2}=-0.625
