Oh, dude, let me break it down for you. So, a centicube is a cube with sides that are 1 cm long. To fill a 3cm by 4cm by 5cm cube, you'd need 3 x 4 x 5 = 60 centicubes. That's like a whole bunch of tiny cubes fitting into a slightly bigger cube.
9cm + 5cm + 9cm + 5cm = 28cm
4cm x 5cm
A rectangular prism is just a box or cuboid So the capacity is 5cm x 4cm x 10cm = 200cm3

3 x 4 x 5 = 60cm3
Yes (apart from units):If the side of a square is 4cm then itsperimeter is 4cm + 4cm + 4cm + 4cm = 4 x 4cm = 16cm;area is 4cm x 4cm = 16cm2
4 x 5cm = 20cm
22 cm

5*3*4 = 60 cm3

To determine the number of triangles with a perimeter of 15cm, we need to consider the possible side lengths that can form a triangle. The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. With a perimeter of 15cm, the possible side lengths could be (5cm, 5cm, 5cm) for an equilateral triangle, (6cm, 5cm, 4cm) for an isosceles triangle, or (7cm, 5cm, 3cm) for a scalene triangle. Therefore, there are 3 possible triangles that can have a perimeter of 15cm.
