Question

A rectangular hole has been dug for a children's swimming pool. It is 7 m long, 4 m wide and 1 m

deep. What is the volume of earth that has been dug out?​

Answer 1

Answer:

$\huge \mp \bf \: given$

• Length of swimming pool - 7 m
• Wide of swimming pool - 4 m
• Height of swimming pool - 1 m

$\huge \mp \bf \: to \: find$

volume of earth that has been dug out

$\huge \mp \bf \: solution$

volume of earth that has been dug out = volume of cuboid

$\bf \: volume \: of \: cuboid \: = l \times b \times h$

$\bf \: volume \: of \: cuboid \: = 7 \times 4 \times 1$

$\bf \: volume \: of \: cuboid \: = {28}^{ 3}$

$\bf \: volume \: of \: earth \: to \: be \: dig \: = {28}^{3}$
