bể hình chữ nhật Một là dài 50 cm, 40cm và rộng 45cm cao.

Chiều cao của mực nước trong container là 15cm

. Làm thế nào nhiều hơn lít nước được yêu cầu phải điền lên xe tăng hoàn toàn?

bài như vậy à

29 tháng 6 2017

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
