Answer 1

$\large\textsf{ {\large\textsf{L.S.A.}}_{\large\textsf{( \; Cuboid \; )}} = \large\textsf{2h ( l + b )} }$

$\large\textsf{ {\large\textsf{T.S.A.}}_{\large\textsf{( \; Cuboid \; )}} = \large\textsf{2 ( lb + bh + hl )} }$

$\large\textsf{ {\large\textsf{Volume}}_{\large\textsf{( \; Cuboid \; )}} = \large\sf{l\times b\times h} }$

$\large\textsf{ }$

$\large\textsf{ {\large\textsf{L.S.A.}}_{\large\textsf{( \; Cube \; )}} = \large\sf{4\times l^2} }$

$\large\textsf{ {\large\textsf{T.S.A.}}_{\large\textsf{( \; Cube \; )}} = \large\sf{6 \times l^2} }$

$\large\textsf{ {\large\textsf{Volume}}_{\large\textsf{( \; Cube \; )}} = \large\sf{l^2} }$

$\large\textsf{ }$

$\large\textsf{ {\large\textsf{C.S.A.}}_{\large\textsf{( \; Cylinder \; )}} = \large\sf{2 \times \pi \; rh} }$

$\large\textsf{ {\large\textsf{T.S.A.}}_{\large\textsf{( \; Cylinder \; )}} = \large\sf{2\pi r \times ( r + h )} }$

$\large\textsf{ {\large\textsf{Volume}}_{\large\textsf{( \; Cylinder \; )}} = \large\sf{\pi r^2h} }$

$\large\textsf{ }$

$\large\textsf{ {\large\textsf{C.S.A.}}_{\large\textsf{( \; Cone \; )}} = \large\sf{\pi rl} }$

$\large\textsf{ {\large\textsf{T.S.A.}}_{\large\textsf{( \; Cone \; )}} = \large\sf{\pi r \times ( r + l )} }$

$\large\textsf{ {\large\textsf{Volume}}_{\large\textsf{( \; Cone \; )}} } \large\textsf{ = \cfrac{\large\textsf{1}}{\large\textsf{3}} }\large\sf{\times \pi r^2h}$

$\large\textsf{ }$

$\large\textsf{ {\large\textsf{T.S.A.}}_{\large\textsf{( \; Sphere \; )}} = \large\sf{4\pi r^2} }$

$\large\textsf{ {\large\textsf{Volume}}_{\large\textsf{( \; Sphere \; )}} } \large\textsf{ = \cfrac{\large\textsf{4}}{\large\textsf{3}} }\large\sf{\times \pi r^3}$
