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
