The total amount of green paint needed to paint 50 trains is 22.5 square meters. Since each tin covers 4 square meters, you need to buy 6 tins of green paint to cover all trains.

The percentage of green paint wasted is 6.25%. Calculate this by finding the difference between the total paint needed and the paint actually used, then dividing by the total paint needed and multiplying by 100.

Porcelain, earthenware, or china clay are the main ingredients used in making cups and saucers. These materials are then shaped, glazed, and fired in a kiln.

Food-grade cardboard, foil-lined cardboard, and sometimes polymers like PET or HIPS are used to create chocolate boxes. These materials are die-cut, embossed, laminated, and printed to create the final box.

Robots are used in manufacturing because they can work continuously without breaks or errors, improving efficiency and reducing costs.

A disadvantage of using robots in manufacturing is the high initial cost of purchasing and maintaining them. Companies must consider the long-term return on investment before making the purchase.

Epoxy resin, contact adhesive, super glue, or no-nails glue are suitable for gluing acrylic numbers onto a wooden clock face.

Epoxy resin is a good choice for this task because it forms a strong bond between dissimilar materials and dries clear, allowing the numbers to be visible.

When using epoxy resin, it's important to wear gloves to avoid skin contact. Wear goggles to protect your eyes from splashes, and ensure proper ventilation to prevent inhaling fumes.

Construction toys are popular with children between 3 and 5 years old, appealing to their creativity and problem-solving skills. This type of toy allows them to build, dismantle, and rebuild structures.

The potential hazard of long hair getting caught in the disc sander can be mitigated by ensuring it's tied back securely, preventing accidents and injuries.

The length of material needed to make one hoop, calculated by using the formula for circumference (C = πD), equals 282.6 mm. Rounding up to the nearest whole millimeter, the final answer is 283mm.

The total material needed for the entire structure includes 3 legs (120 mm each) and 3 hoops (282.6 mm each). Add up all the lengths (360 mm + 847.8 mm = 1207.8 mm). Convert to centimeters: 1207.8 mm = 120.78 cm. Rounding up to the nearest whole centimeter, the final answer is 121 cm.
