The bases of a frustum of a square pyramid are of lengths $10$ units and $6$ units. Its slant height is $10$ units. Find the total surface area of frustum of the pyramid

A hole is to be dug in the form of a frustum of a pyramid. The top is to be a square of side $6.40 \mathrm{m}$ and the bottom a square of $3.60 \mathrm{m}$. The depth of the hole is to be $4 \mathrm{m}$. Calculate the volume of the earth to be removed.

The capacity of the frustum of the pyramid and capacity of the conical bucket is same. If the radii of the circular ends of a conical bucket which is $51 \mathrm{c}\mathrm{m}$ high are $18 \mathrm{c}\mathrm{m}$ and $8 \mathrm{c}\mathrm{m},$ then the capacity of the frustum of pyramid is_____ ${\mathrm{cm}}^3$ $(\text{Use} \mathrm{\pi }=\frac{22}{7})$.

Write the quadrants in which the following points lie:

$\left(-4,7\right)$

A frustum of a pyramid has rectangular ends, and the sides of the base are $25 \mathrm{dm}$ and $36 \mathrm{dm}$. If the area of the top face is $784 \mathrm{sq}.\mathrm{dm}$ and the height of the frustum is $60 \mathrm{dm}$, find its volume.

The frustum of a regular triangular pyramid has equilateral triangle for its bases. The lower and upper base edges are$9 \mathrm{m}$ and $3 \mathrm{m}$ respectively. If the volume is $118.2 \mathrm{cu}. \mathrm{m}$, how far apart (m) are the bases? 

A triangular pyramid which has all the faces as equilateral triangle is _______.
