The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of

AVprozaik [17]

Answer:

surface area of the cube is 96m² and the volume is 64m³

Step-by-step explanation:

Surface area of the cube = 6x²

x is the side length

Given

x = 4metres

Surface area of the cube = 6(4)²

Surface area of the cube = 6(16)

Surface area of the cube = 96m²

Volume of the cube = x³

Volume of the cube = 4³

Volume of the cube = 64m³

Hence the surface area of the cube is 96m² and the volume is 64m³

Find the y-coordinates of the points that are 10 units away from the point (-7, 6) that have an x-coordinate of 1.

prohojiy [21]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-7}~,~\stackrel{y_1}{6})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{y})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ 10=\sqrt{[1-(-7)]^2+[y-6]^2}\implies 10^2=[1-(-7)]^2+[y-6]^2 \\\\\\ 100=(1+7)^2+(y-6)(y-6)\implies 100=8^2+\stackrel{F~O~I~L}{(y^2-12y+36)} \\\\\\ 100=64+36+y^2-12y\implies 100=100+y^2-12y \\\\\\ 0=y^2-12y\implies 0=y(y-12)\implies y= \begin{cases} 0\\ 12 \end{cases}$
