New length = 10cm
New volume = 1000 cm^3
New surface area = 600 cm^2
Step-by-step explanation:
The scale factor is 2
We know the length will be increased by the scale factor
length * scale factor
5cm *2 = 10cm
The new length is 10 cm
The volume will be increased by scale factor cubed
The volume was
V = s^3 = 5^3 = 125 cm^3
V * scale factor
125 * 2^3 = 125 *8 =1000 cm^3
The new volume is 1000cm^3
The surface are is increase by scale factor squared
The surface area was
SA = 6 * s^2
SA = 6*5^2 = 6*25 = 150 cm^2
SA * scale factor
150cm^2 * 2^2
150*4 = 600 cm^2
