Answer 2

Step-by-step explanation:

Given:-

In a rectangular box

length =90cm

breadth=40cm

volume=180litre=180×1000cm^3=180000cm^3

To find:-

height =h

Solution:-

as we know that in a rectangular box

${:}\longrightarrow$${\boxed{volume=lbh}}$

${:}\longrightarrow$$180000=90×40×h$

${:}\longrightarrow$$[tex]180000=3600h$

${:}\longrightarrow$$h={\frac {180000}{3600}}$

${:}\longrightarrow$${\underline{\boxed{\bf{h=50cm }}}}$
