प्रश्न
The length of the diagonals of a cube is 8√3 cm.
Find its:
(i) edge
(ii) total surface area
(iii) Volume
उत्तर
(i) Length of diagonal of a cube = `8sqrt(3)` cm
Length of edge = `(8sqrt(3))/sqrt(3)` = 8 cm
(ii) Total surface area = 6a2 = 6 x 82 = 6 x 64 cm2 = 384 cm2
(iii) Volume = a3 = (8)3= 512 cm3
