Chiều cao của bể là 45 cm mà hiện tại mực nước của bể chỉ cao 15 cm.
Nên chiều cao của số phần nước chưa có trong bể là :
45 - 15 = 30 ( cm )
Muốn tìm được số l nước cần đổ thêm ta lấy dài x rộng x cao: ( chú ý : đơn vị phải là dm khối )
(=) 50 x 40 x 30 = 60 000 ( cm khối ) = 60 dm khối = 60 lít nước ( do 1 dm khối = 1 lít nước )
Vậy số lít nước cần đổ thêm là 60 lít nước
