Find the volume, total surface area, lateral surface area and the length of diagonal of a cube, each of whose edges measured 20 cm |
|
Answer» Here, a = 20 cm Volume of the cube `= a^(3)` cubic units `= (20xx 20xx 20) cm^(3) = 8000 cm^(3)` Total surface area of the cube `= (6a^(2))` sq units `= (6 xx 20 xx 20) cm^(2) = 2400 cm^(2)` Lateral surface area of the cube `= (4a^(2))` sq units `= (4 xx 20 xx 20) cm^(2) = 1600 cm^(2)` Diagonal of the cube `= (sqrt3a)` units `= (sqrt3 xx 20) cm = (1.732 xx 20) cm` = 34.64 cm |
