Question
Find the volume, lateral surface area and the total surface area of a cube whose edges measures:
$5.6cm.$
$5.6cm.$
✓
Answer
Edge of cube $(a)=5.6 cm$.
a. Volume $=a^3=(5.6)^3 cm^3$
$=5.6 \times 5.6 \times 5.6 cm^2=175.616 cm^3$
b. Lateral surface area $=4 a ^2$
$=4(5.6)^2=4 \times 5.6 \times 5.6 cm^2$
$=125.44 cm^2$
c. Total surface area $=6 a ^2=6 \times(5.6)^2 cm^2$
$=6 \times 5.6 \times 5.6 cm^2=188.16 cm^2$
a. Volume $=a^3=(5.6)^3 cm^3$
$=5.6 \times 5.6 \times 5.6 cm^2=175.616 cm^3$
b. Lateral surface area $=4 a ^2$
$=4(5.6)^2=4 \times 5.6 \times 5.6 cm^2$
$=125.44 cm^2$
c. Total surface area $=6 a ^2=6 \times(5.6)^2 cm^2$
$=6 \times 5.6 \times 5.6 cm^2=188.16 cm^2$
