I assume you're asking for the scale? It would be 4:64, which simplifies to 1:16.
Answer: 525kg
Step-by-step explanation:
To decrease 700kg by 25% implies
700 - 25% of 700kg
25% of 700 = 25/100 × 700kg
0.25 x 700
= 175
Therefore, to decrease 700kg by 25%, since 25% is 175kg, we subtract 175kg from 700kg
700kg - 125kg
= 525kg
The amount of water needed to fill the swimming pool completely is 864 cubic meters.
Given that each of the four sides of a swimming pool measures 12 m the pool is 6 m deep.
"Volume" is a mathematical quantity that indicates the amount of three-dimensional space occupied by an object or surrounding surface. Volume units are cubic units like m³, cm³, in³, etc.
As we know, the swimming pool is in cubic shape.
So, we will find the volume of cube using the formula V=l×b×h.
Here, l=12m, b=12m and h=m.
Now, we want to substitute the values in the formula, we get
V=12m×12m×6m
V=864m³
Hence, the amount of water needed to fill completely the swimming pool whose each of the four sides of a swimming pool measures 12 m the pool is 6 m deep is 864 cubic meters.
