answer ⤵️

For a square pyramidBase edge =s=12cm

Slant height =l=10cm

Since the base of the pyramid is square,Therefore, a= diagonal/2

Diagonal of square of base is

12 \sqrt{2}  \: cm

a =   6\sqrt{2}

h \:  =  \sqrt{ {10}^{2} +  {a}^{2}  }

 =  \sqrt{ {10}^{2}  - 6 \sqrt{  {2}^{2} }^{2} } }

 \sqrt{100 - 72 }

 =  \sqrt{18}

Volume= 1/3s square h

=1/3*18*18

144 \sqrt{22}

Hope itz help you....
