A cube of side 6 cm is painted with blue colour and cut into small cubes of side 1 cm, the small cubes which has no painted side is painted with red colour. And the remaining areas of remaining small cubes are painted with green colour. Find the ratio of blue painted, red painted and green painted area.
Two opposite faces of a large cube are painted red, two adjacent faces are painted yellow and the rest of the faces are painted blue. On each axis of this big cube, 4 equal cuts have been made and some smaller cubes have been obtained. How many such small cubes will be there in which one face is painted blue and one is painted yellow?
Consider the following statements and choose the correct answer:
1. A direct proportionality exists between vapour pressure and the concentration of water vapour in the atmosphere
2. Relative humidity is an expression of the ratio of the actual vapour pressure of the atmosphere when saturated at the same temperature
3. A rise or fall in temperature with no change in vapour pressure will cause a drop or rise, respectively, in relative humidity
4. A rise or fall in vapour pressure with no change in temperature will be accompanied by a rise or fall, respectively, in relative humidity
The pairs of opposite faces of a large cube are painted red, yellow and blue. Now 3 equal cuts are made on each side of this cube and some smaller cubes have been obtained. How many such small cubes will be there in which one face is painted yellow, one face is painted red or blue and all other faces are not painted?
A cube of volume 64 cm3 is is cut into two smaller and identical cuboids. The faces of dimensions 4 × 4 of one of the cuboids are painted with black color and the rest of its faces are painted with yellow color. One pair of adjacent faces that do not include any face of dimensions 4 × 4 of the other cuboid are painted with yellow color and the rest of its faces are painted with black color. Now each of two cuboids are cut into 32 smaller and identical cubes. How many of the smaller cubes have exactly three colored faces?
A, B and C can alone paint a room in 40 hours, 60 hours and 80 hours respectively. If A, B and C together painted the wall for 10 hours, then A left and B and C together painted for 4 hours, then B left but A returned and A and C together painted for 8 hours, then what part of the wall is still left to be painted?
The six faces of a solid cube have been painted in different colours. The top of the cube is painted Red and the bottom is painted White. The rest of the four faces have been painted Yellow, Blue, Green and Pink, respectively in clockwise direction. The cube is now turned in such a manner that Blue face is at the top. What will be the colour of the bottom face?
