The formula for the volume of a pyramid is:
V = (l * w * h) / 3
knowing the formula we can replace the letters with the values we know:
v = 162
h = 6
since they told us the pyramid is square, we know that both L and W would be the same, so now we CAN SAY L *W = L^2 and solve for that:
162 = (l^2 * 6) / 3
multiply both sides by 3
486 = l^2 * 6
divide both sides by 6:
81 = l^2
l = sqrt(81)
l = 9 feet
1/6
Turn into decimal:-
1 ÷ 6 = 0.16
1/6 = 0.16

Hello!
First you will want to get both of equations into slope-intercept form. That way, you can easily determine the y-intercept of the first equation and the slope of the second equation.
When 2 lines have the same slope, that means they will be parallel.
y+4x-10=0 ; add 10 to each side
y+4x=10 ; subtract 4x from each side
y = -4x + 10 ; y-intercept = 10
1x + 7y = 6 ; subtract 1x from each side
7y = -1x + 6 ; divide both sides by 7
y = -1/7 x + 6/7 ; slope = -1/7
So, a line with the same y-intercept as the first, and same slope (parallel) as the second would have the equation:
y = -1/7x + 10
