Given that the dimensions are external dimensions and that the steel plate is 2 cm thick,calculate the mass of the tank if the density of the steel is 7·8 g/cm3.Give the answer correct to one decimal place.

首先要先求体积,
这个容器的体积相当于外围的大长方体,减去中间空心部分的体积,
也就是
3.5×10.5×2.4 - (3.5-0.04)×(10.5-0.04)×(2.4-0.02)
= 88.2 - 86.14 = 2.06(m^3)
然后根据M = mg求质量,
所求为
M = 7.8 × 2.06 × 10^6
= 16.068 × 10^6 g
= 16.068 t
= 16.1 t
题目要求取一位小数,所以所求为16.1t,也就是16.1吨.
希望有用.
