The surface area of a cube is \( \Large 1350\ cm^{2} \). The length of the diagonal is.
Correct Answer: |
|
C) \( \Large 15\sqrt{3} \)cm |
|
Description for Correct answer:
Surface area of the cube = \( \Large 1350\ m^{2} \)
\( \Large 6a^{2}=1350 \)
\( \Large a^{2}=\frac{1350}{6}=225 \)
\( \Large a = \sqrt{225} = 15 \)
The length of the diagonal =\( \Large a\sqrt{3} = 15\sqrt{3} \)
