Volume of a rectangular prism is WHL
Volume of a rectangular prism is <span>0.3 m * 2.1 m * 0.1 m
</span>Volume of a rectangular prism is 0.063
x=6
if you multiply 4 by whats inside the parenthesis you get 5x+16x+44=170
next combine like terms and get 21x+44=170
next subtract 44 from itself and 170 to get 21×=126
finally divide 21 from both sides and you get x=6
