Find the volume of a cuboid whose length is 8 cm, breadth 6 cm and height 3.5 cm.
Find the volume of a cuboid whose length is 8 cm, width is 3 cm and height is 5 cm.
140 x 2450 = 343000
Cube root of 343000 = (343000)^{1/3} = (70^{3})^{1/3 }= 70
A rectangular paper of width 7 cm is rolled along its width and a cylinder of radius 20 cm is formed. Find the volume of the cylinder.
Top surface of a raised platform is in the shape of regular octagon as shown in the figure. Find the area of the octagonal surface.
This regular octagon can be into two trapeziums (each having height 4 m and parallel sides as 11 m and 5 m) and a rectangular part with length 11 m and breadth 5 m.
The diagonal of a quadrilateral shaped field is 24 m and perpendicular dropped on it from the remaining opposite vertices are 6 m and 12 m. Find the area of the field.
area=1/2×d×(h_{1}+h_{2})
=1/2×24×(12+6)
=12(18)
=216 m^{2}
If the parallel sides of a parallelogram are 2 cm apart and their sum is 10 cm then its area is:
If the edge of a cube is 1 cm then which of the following is its total surface area?
Find the area of a triangle whose base is 4 cm and altitude is 6 cm.
We know that area of triangle is equals to 1/2 base × altitude.
Here, base = 4 cm and altitude = 6 cm.
So, area = 1/2 × 4 × 6= 24 /2= 12 cm^{2}.
