Answer:
225 cm²
Explanation:
The container has 2.7L of water in it but it is only 4/5 full
Therefore if the container were to be filled entirely with water it would contain
2.7 x 5/4 = 3.375 Liters
This, therefore is the volume of the container is 3.375 L
3.375 L = 3.375 x 1000 cm³
= 3, 375 cm³
The volume of a cube of side a is given by
V = a³
The base area of a cube of side a is given by
A = a²
We have calculated the volume of the cube as 3.375 cm³
Therefore each side of the cubical container
![a = \sqrt[3]{3375} = 15](https://img.qammunity.org/2024/formulas/mathematics/high-school/a4dzb7thqc1bt9nfy1e8eiblm9vmk70zsn.png)
cm
The base area is
a² = 15²
= 225 cm²
