R. D. Sharma Solutions for Chapter: Surface Area and Volume of a Cuboid and Cube, Exercise 3: VERY SHORT ANSWER TYPE QUESTIONS (VSAQs)

If two cubes each of side $6 \mathrm{cm}$ are joined face to face, then the volume of the resulting cuboid$=$_____${\mathrm{cm}}^3$.

Three cubes of metal whose edges are in the ratio $3:4:5$ are melted down into a single cube whose diagonal is $12\sqrt{3}\mathrm{cm}$. Find the edges of three cubes.

If the perimeter of each face of a cube is $32 \mathrm{cm},$its lateral surface area$=$_____${\mathrm{cm}}^2$. Note that four faces which meet the base of a cube are called its lateral faces.

The edge of a cube whose surface area is $432 {\mathrm{m}}^2$ is $k\sqrt{2}\text{m}$ . Find the value of k.

A cuboid has total surface area of $372 {\mathrm{cm}}^2$ and its lateral surface area is $180 {\mathrm{cm}}^2$, the area of its base$=$_____${\mathrm{cm}}^2$.

Three cubes of each side $4 \mathrm{cm}$ are joined end to end. If the surface area of the resulting cuboid is $k {\mathrm{cm}}^2$, find $k$.

The surface area of a cuboid is $1300 {\mathrm{cm}}^2.$ If its breadth is $10 \mathrm{cm}$, height is $20 \mathrm{cm}$ and length is $k \mathrm{cm}$, find $k$.
