Peter molded a cuboid 2 cm, 4cm, 9cm of plasticine. Then the plasticine split into two parts in a ratio 1:8. From each piece made a cube. In what ratio are the surfaces of these cubes? - Cube edges

If the edge length of the cube increases by 50%, how does the volume of this cube increase? - Rate or interest

At what rate percent will Rs.2000 amount to Rs.2315.25 in 3 years at compound interest? - Cube surface area

The surface of the cube was originally 216 centimeters square. The surface of the cube has shrunk from 216 to 54 centimeters sq. Calculate how much percent the edge of the cube has decreased. - Sugar cubes

The glass has 600 ml of tea, which represents 80% of the volume of the glass. If you put twenty regular sugar cubes of 2 cm in the tea, how many ml of tea are poured? - Scale factor

A prism with a volume of 1458 mm³ is scaled down to a volume of 16mm³. What is the scale factor in fraction form? - Tower model

Tower height is 300 meters, weight 8000 tons. How high is the model of the tower's weight of 1 kg? (State the result in the centimeters). The model is made from exactly the same material as the original no numbers need to be rounded. A result is a three-d - Cube

One cube has an edge increased five times. How many times will larger it's surface area and volume? - Surface of wall

Find by what percentage the surface of the cube will decrease if we reduce the surface of each of its walls by 12%. - Z9-I-4

Kate thought a five-digit integer. She wrote the sum of this number and its half at the first line to the workbook. On the second line wrote a total of this number and its one fifth. On the third row, she wrote a sum of this number and its one nines. Fina - Prism bases

Volume perpendicular quadrilateral prism is 360 cm³. The edges of the base and height of the prism are in the ratio 5:4:2. Determine the area of the base and walls of the prism. - Inscribed sphere

How many % of the volume of the cube whose edge is 6 meters long is a volume of a sphere inscribed in that cube? - Surface area 2

Calculate how many % reduce the surface area of the cube is we reduced length of each edge by 10%. - Reduce of the volume

Calculate how many % reduce the volume of the cube is we reduced length of each edge by 10%. - Lathe
