The edges of a cubical frame are made from plastic straws. How much longer is the total length of the plastic edges of a cube whose edge is 10cm comparednto a cube whose edge is 8cm?

Sagot :

A cube has 12 edges:

First cube has 10 cm edge, while the smaller cube has 8 cm edge.  Subtract the measure of total length of their edges:

(12 × 10 cm) - (12 × 8 cm) = difference of total length their edges
120 cm - 96 cm = 24 cm

Final Answer:  The total length of edges of bigger cube (with 10 cm edge) is longer by 24 cm than the smaller cube.
