A solid rectangular box with height 5 m and square base with side lengths 4 m is built using a lightweight material whose densit
elena55 [62]

Answer:

627200LJ

Step-by-step explanation:

Height of box=5 m

Side of square base=4 m

Volume of rectangular box=l\times b\times h

Using the formula

Volume of rectangular box=4\times 4\times 5=80m^3

Density of material=800kg/m^3

We know that

Mass=Density\times volume

Using the formula

Mass of  rectangular box=80\times 800=64000 kg

Gravity=g=9.8m/s^2

Weight of  rectangular box,F=mg=64000\times 9.8 N

Let L  be the vertical distance traveled by box

Total work done =W=F\times displacement

Therefore,total work done against gravity =64000\times 9.8 L=627200 L J

Hence, the box requires work against gravity=627200LJ

A technical machinist is asked to build a cubical steel tank that will hold of water. Calculate in meters the smallest possible
Charra [1.4K]

Answer:

The smallest possible length is 0.83m

Step-by-step explanation:

Given

Volume = 565L

Required

The smallest length of the tank

Since the tank is cubical, then the volume is:

Volume = Length^3

This gives:

565L= Length^3

Express as m^3

\frac{565m^3}{1000} = Length^3

0.565m^3 = Length^3

Take cube roots of both sides

0.8267m = Length

Rewrite as:

Length = 0.8267m

Approximate

Length = 0.83m

A system of equations is shown below:
JulijaS [17]
X+y=3

Subtract x from both sides

y=-x+3

Substitute

2x--x+3=6
2x+x+3=6
3x+3=6

Subtract 3 from both sides

3x=3

Divide both sides by 3

x=1
