A block of ice weighs 12 tonne. The block is a cube with side length 81cm.
Find the density of the ice.
Give your answer in kilograms per cubic metre.

81 cm is 0.81 metre

12 tonne is 12000 kg

Volume of a cube is a^3

V=0.531441

D=M/V

=12000/0.531441

Density is 22580.11708 kg per m cube

Step-by-step explanation:

idk bring the function back   im not smart

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
