The  surface area  and  volume  of the  real brick  will be  983.2 cm² and  1738.11 cm³  respectively.    What is volume?    The term “ volume ” refers to the  amount  of three- dimensional  space taken up by an item or a  closed surface . It is denoted by  V  and its  SI unit  is in  cubic cm .    The  scale factor  is ;    r = 630 cm /23   r = 27    L = 23 cm  b = 310 / 27 = 11.48 cm  h = 180/27 = 6.6 cm    The  surface area  of the  brick ;    A = 2(lb+bh+hl)  A = 2( 23 ×11.48+11.48×6.6+6.6×23)  A= 983.2 cm²    The  volume  of the  brick  is;    V= lbh  V=23 × 11.45 ×6.6  V=1738.11 cm³    Hence the  surface area  and  volume  of the  real brick  will be  983.2 cm²  and  1738.11 cm³  respectively.
