Question
Find the volume, lateral surface area and the total surface area of a cube whose edges measures:
7m.
7m.
✓
Answer
Edge of cube (a) $=7 m$
a. Volume $=a^3=(7)^3$
$=7 \times 7 \times 7 m^3$
$=343 m^3$
b. Leteral surface area $=4 a ^2$
$=4(7)^2=4 \times 49 m^2=196 m^2$
c. Total surface area $=6 a^2=6(7)^2 m^2$
$=6 \times 49=294 m^2$
a. Volume $=a^3=(7)^3$
$=7 \times 7 \times 7 m^3$
$=343 m^3$
b. Leteral surface area $=4 a ^2$
$=4(7)^2=4 \times 49 m^2=196 m^2$
c. Total surface area $=6 a^2=6(7)^2 m^2$
$=6 \times 49=294 m^2$
