Answer:we know that,
Answer:we know that,Volume of cuboid= Length× bredth× height
Let the bredth be x.
given,
Length= 9cm
Height= 4cm
surface area of brick= 202² cm.
According to the question,
surface area of brick= 2( lb+bh+hl)
=) 202= 2( 9x+4x+36)
=) 202= 2(13x+ 36)
=) 202= 32x+72
=) 202- 72= 32x
=) 130= 32x
=) x= 130/32
=) x= 4.06cm
therefore, bredth= 4.06 cm.
Thus,
Volume of brick= Length×bredth× heigh
=9cm×4.06cm×4cm
= 146.16cm³
