Answer:
1.length = 15, width = 12, height = 13
2. 13 × 12 × 15 = 2340
Step-by-step explanation:
3 ÷ 1/4 = 12
3 3/4 = 15/4
15/4 ÷ 1/4 = 15
3 1/4 ÷ 1/4 = 13
length = 15
width = 12
height = 13
13 × 12 × 15 = 2340
Let w = width
then
5w-3 = length
w(5w-3) = 14
5w^2-3w = 14
5w^2-3w-14=0
(5w+7)(w-2) = 0
w = {-7/5, 2}
throw out the negative solution leaving
w = 2 centimeters
length:
5w-3 =5(2)-3 =10-3 = 7 centimeters
