Calculate the density of a rectangular piece of wood from the following data:

length: 25 cm. width: 10 cm. height: 4 cm. mass: 15 g
a.

0.015 g/cm3

c.

0.015 g/ml
b.

10.015 g/ml

d.

none of the above

Step-by-step explanation:

Formula for density =

As per given , dimensions of a rectangular piece of wood:

Length: 25 cm. Width: 10 cm. Height: 4 cm.

Mass: 15 g

Volume of rectangular piece = Length x width x height

= 25 x 10 x 4 = 1000 cubic cm

Now , density =

Hence, the correct option is

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
