Surface are of a rectangular prism = 2(l x w + l x h + w x h) = 2(10 x 3 + 10x + 3x) = 2(30 + 13x) = 60 + 26x
Volume of a rectangular prism = l x w x h = 10 * 3 * x = 30x
Since surface area = volume
60 + 26x = 30x
4x = 60
x = 15 in
First number = X
second number = x +26 ( exceeds means higher so add 26)
x + x+26 = 58
combine like terms:
2x + 26 = 58
subtract 26 from each side:
2x = 58-26
2x = 32
divide both sides by 2:
x = 32/2
x = 16
first number is 16
second number = 16+26 = 42
You will use the ratio 4:8 to create a part to part to whole ratio.
First simplify 4:8 to 1:2, then make it 1:2:3 (Salt:Sugar:Total).
Use this to find the volume of sugar. 2 sugars for every 3 total would be equivalent to 200 cubic feet of sugar for every 300 total cubic feet.
Answer:
the answer is that of equations 1
