find the total surface area and lateral surface area of the cube , if edge=14.2cm
Answers
Total Surface area of cube = 6a²
- a denotes edge of cube
- Edge of cube = 14.2 cm
TSA of cube = 6a²
TSA of cube = 6(14.2)²
TSA of cube = 6(201.64)
TSA of cube = 1209.84 cm³
Lateral Surface area of cube = 4a²
- a denotes edge of cube
- Edge of cube = 14.2 cm
LSA of cube = 4a²
LSA of cube = 4(14.2)
LSA of cube = 4(201.64)
LSA of cube = 806.56 cm³
Answer:
total surface area = 1,209.84cm. sq. , lateral surface area = 806.56cm. sq.
Step-by-step explanation:
total surface area of a cube = 6xsq.
here x = 14.2
according to the formula = 6× 14.2sq.
= 6 × (14.2×14.2)
= 6×201.64
= 1,209.84 cm. sq.
lateral surface area of a cube = 4xsq.
here x = 14.2
according to the formula = 4× 14.2sq.
= 4× (14.2×14.2)
= 4×201.64
= 806.56 cm. sq.
