Answer: 2 feets
Step-by-step explanation:
Recommended density = 7 fish/ ft^3
If recommended density guideline is followed:
Number of fishes in aquarium = 42
Length of aquarium = 3ft
Width = 1ft
Height =?
Volume of aquarium = Length × width × height
Volume = 3 × 1 × h = (3ft^2 × h)
Therefore ;
If
1ft^3 = 7 fishes
x ft^3 = 42 fishes
Cross multiply
7(x)ft^3 = 42 fishes
x ft^3 = (42÷7)
x ft^3 = 6
Therefore volume of the aquarium with 42 fishes is 6ft^3
Volume = (3ft^2 × h)
6ft^3 = 3ft^2 × h
h = (6ft^3) / (3ft^2)
h = 2ft
U multiply it as u would multiply a two digit and a one digit number step by step only then u have to multiply the second number like u did to the other number and u add a zero then add them and u get ur answer
1. 5+6>8
6+8> 5
5+8> 6
2. 10+10> 2
10+2> 10
10+2> 10
3. 19+ 34> 15
19+ 15 > 34 not correct
34+15 > 19
4. 3+16 > 14
3+14> 16
14+16 >3
