Answer 1

HEY......☺

EACH EDGE OF CUBE IS 8CM.....

MEANS ITS SIDE IS 8CM.....

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

NOW,

VOLUME OF CUBE = SIDE ^3

VOLUME = 8^3

VOLUME = 8*8*8

VOLUME = 512 CM^3

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

LATERAL SURFACE AREA OF CUBE

= 4*SIDE^2

= 4 * 8^2

= 4 * 8 * 8

= 32 * 8

= 256 cm^2

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

TOTAL SURFACE AREA OF CUBE

= 6 * SIDE ^ 2

= 6 * 8^2

= 6 * 8 * 8

= 384 cm^2
