A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.

Papessa [141]

Answer:

$\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}$

Step-by-step explanation:

Given dimensions of the box = 20cm × 6cm × 4cm .

Dimension of the cube = 2cm × 2cm × 2cm .

Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,

$\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}$

$\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }$

<h3>Hence the number of cubes that can be fitted in the box is 60 .</h3>

Answer:

The slope is $-50$ . The slope means that the amount of money in the account is decreasing at a rate of $ $50$ every week.

Step-by-step explanation:

Given coordinates are $(4,2400)\ and\ (12,2000)$

We need to find the slope of the graph, and explain what does slope means for this graph.

The formula for computing slope $(m)$ is

$m=\frac{y_2-y_1}{x_2-x_1}$

Where $(x_1.y_1)$ and $(x_2,y_2)$ are the point on the line.

Let us plug points $(4,2400)\ and\ (12,2000)$ in the equation

$m=\frac{2000-2400}{12-4}\\ \\m=\frac{-400}{8}\\\\m=-50$

Here, the negative sign of slope $(m)$ represents that the value of the function (budget) is decreasing, with an increase in time (week).

The slope is $-50$ . The slope means that the amount of money in the account is decreasing at a rate of $ $50$ every week.

Answer:

598=194+8x

Step-by-step explanation:

To solve you would subtract 194 from its self and 598

598=194+8x

-194 -194

404=8x

then you would divide 8 from it's self and 404

which would make it 50.5

(but you cant buy half a package of spoons so realistically it'd be 50 or 51.

hope this helped :)
