a ) Thể tích bể bơi đó là :
8,2 x 4,8 x 2 = 78,72 ( m3 )
Bạn chỉ cần lấy V của bể bơi chìa cho V của gạch men là ra à !Mà nếu chỉ lát ở chỗ Stp của bể bơi thì lấy S từng mặt một chia cho S gạch men .Thế nhé !Chúc bạn học giỏi!
chu vi chiều dài và chiều rộng là:
9:1.5=6m
tổng chiều dài và chiều rộng là :
6;2=3m
chiều rộng là :
(3-0.6):2=1.2m
chiều dài là :
1.2+0.6=1.8m
thể tích bể nước là :
1.8x1.2x1.5=3.24m3
