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 compared to a cube whose edge is 18cm?

Well, well, well, straws and cubes! I'm always up for a good challenge. Now, let's dive into the math with a splash of humor!

To find the total length of the plastic edges, we need to know how many edges a cube has. And lucky for us, a cube has 12 edges. So let's get counting!

For a cube with an edge of 10cm, the total length of all its edges would be 12 * 10cm = 120cm. Easy-peasy!

Now, for the bigger cube with an edge of 18cm, we can apply the same formula: 12 * 18cm = 216cm.

So, to find the difference in lengths, we subtract the length of the smaller cube from the length of the larger cube: 216cm - 120cm = 96cm.

Ta-da! The total length of the plastic edges is 96cm longer for the cube with an edge of 18cm compared to the cube with an edge of 10cm. Quite the stretch, eh?

To find the difference in the total length of the plastic edges between the two cubes, let's calculate each separately and then find the difference.

For a cube with an edge length of 10cm:
The total length of the plastic edges can be calculated by multiplying the number of edges (12) by the length of each edge (10cm).
Total length of plastic edges = 12 * 10cm = 120cm

For a cube with an edge length of 18cm:
The total length of the plastic edges can be calculated by multiplying the number of edges (12) by the length of each edge (18cm).
Total length of plastic edges = 12 * 18cm = 216cm

Now, let's find the difference between the total lengths of the plastic edges:
Difference = Total length of plastic edges for 18cm cube - Total length of plastic edges for 10cm cube
Difference = 216cm - 120cm
Difference = 96cm

Therefore, the total length of the plastic edges of a cube with an edge length of 10cm is 96cm less than a cube with an edge length of 18cm.

To find the total length of the plastic edges of a cube, we can add up the lengths of all the edges. In a cube, each edge has the same length.

So, let's first find the total length of the cube with an edge length of 10 cm:

Since a cube has 12 edges, each with a length of 10 cm, the total length would be 12 * 10 cm = 120 cm.

Now, let's find the total length of the cube with an edge length of 18 cm:

Similarly, since a cube has 12 edges, each with a length of 18 cm, the total length would be 12 * 18 cm = 216 cm.

To determine how much longer the total length is for the cube with an edge length of 10 cm compared to the cube with an edge length of 18 cm, we subtract the total length of the smaller cube from the total length of the larger cube:

216 cm - 120 cm = 96 cm.

Therefore, the total length of the plastic edges of the cube with an edge length of 10 cm is 96 cm longer compared to the cube with an edge length of 18 cm.

How many edges does a cube have? Multiply that number by (18-10).
