Given,
Diagonal = 9√3 cm
To find,
The total surface area of the cube.
Solution,
The total surface area of the cube whose diagonal is 9√3 cm is 486 cm².
We can simply find the total surface area of the cube by using the formula of the total surface area of the cube which is 6a².
Diagonal = √3side
9√3 = √3 side
9 cm = side
a = 9
Total surface are of the cube = 6a²
= 6*9*9
= 486 cm²
Hence, the total surface area of the cube whose diagonal is 9√3 cm is 486 cm².
