Question

Find the area of a cube whose one side measure 5cm and one diagonal is 8cm.​

Answer 1

As per the data given in the question,

In the above question, it is given that,

The one side of a cube is $=5cm$

One diagonal of a cube is $=8cm$

Here we have to use the formula of area of cube.

Thus,

Area of a cube$=6a^{2}$

where a is the side of the cube,

Therefore,

$A=6\times (5)^{2} \\A=6\times 25\\A=150cm^{2}$

Hence the area of a cube is $150cm^{2}$

Answer 2

As per the given data in the question

We have find the value of given expression

Given the area of cube whose one side measure 5 cm and one diagonal

is 8 centimeter

The use of formula Area of cube

Hence, Area of cube $=6a^{2}$

Further ,$\Rightarrow A=6*(5)^{2}\\\Rightarrow A=6*25\\\Rightarrow A=150 cm^{2}$

Hence the area of cube will be $A=150cm^{2}$ .
