Question

qual o volume da caixa d agua. ?

Answer 1

$V_p(b,h,l)=b\cdot h \cdot l\implies\\b=base\\h=altura\\l=largura\\\\b=40cm\\h=25cm\\l=30cm\\\\V_p(40cm,25cm,30cm)=40cm\cdot 25cm\cdot30cm=\boxed{30000cm^3}\\capacidade~total~da~caixa~e~30000cm^3,~30000cm^3=30l$

Answer 2

v=l x w x h
v=40x30x25
v=30000
