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

What is the answer tie this problem (show ALL work please and thankyou) 1/3(18+12q)=6(2q-7)

qaws [65]

$\frac{1}{3}$ (18 + 12q) = 6(2q - 7) Use the Distributive Property on both sides
6 + 4q = 12q - 42 Subtract 12q from both sides
6 - 8q = -42 Subtract 6 from both sides
-8q = -48 Divide both sides by -8
q = 6
