Problema Solution
an aquarium holding African chichilds is 3 in higher than it is wide it's length is 27 inchs and it's volume 3510 cubic inches. what is the height and width of the aquarium
Answer provided by our tutors
Height, width =w. Then Volume = 27*w*(3+w) = 3510.
So, 3w+w2 = 3510/27= 130.
So, w2 + 3w -130 = 0 => w = 10 or w = -13.
So, w = 10 inches.
So, height = 13 inches
