Question 194474
{{{ y = (-2/225) x^2  + 50 }}} 
.
Find y-intercept, set x=0 and solve for y:
{{{ y = (-2/225) x^2  + 50 }}} 
{{{ y = (-2/225) 0^2  + 50 }}} 
{{{ y = 50 cm}}}
.
Find x-intercept, set y=0 and solve for x:
{{{ y = (-2/225) x^2  + 50 }}} 
{{{ 0 = (-2/225) x^2  + 50 }}} 
{{{ -50 = (-2/225) x^2 }}} 
{{{ 50 = (2/225) x^2 }}} 
{{{ (50*225)/2 = x^2 }}} 
{{{ (25*225) = x^2 }}} 
{{{ 5625 = x^2 }}} 
+-75 cm = x 
.
Therefore, the dimensions of the box:
150 cm X 150 cm X 50 cm
