Abrick has dimensions of 15 cm by 6.0 cm by 12 cm what is the volume of the brick in cubic meters

 The  volume   of  the brick  in cubic   meters  is 0.00108 m³

 calculation

volume of a brick  =length  x  width   x  height

-length = 15 cm

width = 6.0 cm

height = 12 cm

volume is therefore= 15 cm x 6.0 cm   x 12 cm =1080 cm³

convert  1080 cm³ into m³

that  is  1 cm³  =  1  x 10^-6m³

        1080  cm³ = ? m³

by cross multiplication

=[ (1080 cm³  x 1 x10^-6 m³)  /  1 cm³]  =  0.00108 m³

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

the answer is barium and copper bromide
