The dimensions of a cuboid are 5cm, 3cm and 2cm. Draw three different isometric sketches of this cuboid.

A pen stand made of wood is in the shape of a cuboid with four conical depressions to hold pens. The dimensions of the cuboid depressions are 15 cm by 10 cm 3.5 cm. The radius of each of the depressions is 0.5 cm and the depth is 1.4cm . Find the volume of wood in the entire stand ( see fig ).

The dimensions of a block are 1 cm xx 1 cm xx 100 cm . If specific resistance of its material is 3 xx 10^-7 ohm metre then the resistance between the opposite rectangular faces is :

Three circles with centres A,B and C touch each other as shown in the figure .If the radii of these circle are 8cm ,3cm and 2cm respectively,then the perimeter of DeltaABC is :

Three circles of radii 4 cm ,3cm and 2cm touch each other externally.The perimeter of the triangle formed by joining their centre is:

Three cubes of sided 3 cm, 4cm, and 5 cm are melted and recast into a cube. a] find the length of the cube. b] find the surface area of the cube.

Radii of two circles are 5 cm and 3 cm respectively and the distance between their centres is 6 cm.

A spherical ball of radius 3 cm is melted and recast into three spherical balls. The radii of two balls are 1.5 cm and 2 cm. find the diameter of the third ball.

The lengths of three consecutive sides of a quadrilateral circumscribing a circle are 4 cm, 5 cm, and 7 cm respectively . Determine the length of the fourth side.
