Step-by-step explanation:

Given: The dimension of a cuboid

$l(length)=6.2m\\w(width)=2.4m\\h(height)=2.5m$

To Determine: The volume of the container

The volume of a cuboid is calculated by the formula below:

$V cuboid=lxwxh$

Substitute into the formula the given dimensions

If a shape has triple the dimensions of a similar shape then it has _______ the area *

IrinaK [193]

Answer:

9 times

Step-by-step explanation:

The best way to go about this is to give actual figures

Let us consider rectangular shape

Let us have a rectangle with dimensions 6 m by 12 m

The area will be 6 * 12 = 72 m^2

The shape having a similar dimension would have dimensions 12m by 36 m

So its area will be ;

18 * 36 = 648 m^2

So we finally proceed to make a division

Mathematically, that will be 648/72 = 9

So the area will be in the ratio of 1 to 9
