A Wooden cube is 4 cm is cut into 1 cm cubes.What is the percentage increase in the surface area after such cutting?
Answers
Answer:
300%
Step-by-step explanation:
Total surface area of 4 cm³ = 6(4)²
= 96 cm².
∴ Number of 1 cm cubes obtained by cutting the 4 cm cube:
= (4)³/(1)³
= 64.
The total surface areas of all the 1 cm cubes = 64 * 6
= 384 cm²
Increase in the total surface area = 384 - 96
= 288.
% increase in the total surface area = (288/96) * 100
= 300%.
Hope it helps!
