Answer:
True
Step-by-step explanation:
Volume is calculated by length x width x height, so you just multiply the values. 6 x 7 x 9 = 378 cm^3.
so a box will be a rectangular prism, and thus its volume will simply be the product of its length, width and height.
let's firstly convert the mixed fractions to improper fractions and the multiply.
![\bf \stackrel{mixed}{1\frac{2}{3}}\implies \cfrac{1\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{5}{3}}~\hfill \stackrel{mixed}{2\frac{1}{3}}\implies \cfrac{2\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{7}{3}} \\\\[-0.35em] ~\dotfill\\\\ \textit{volume of a rectangular prism}\\\\ V=Lwh~~ \begin{cases} L=\frac{7}{3}\\ w=2\\ h=\frac{5}{3} \end{cases}\implies V=\cfrac{7}{3}\cdot 2\cdot \cfrac{5}{3}\implies V=\cfrac{70}{9}\implies V=7\frac{7}{9}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7Bmixed%7D%7B1%5Cfrac%7B2%7D%7B3%7D%7D%5Cimplies%20%5Ccfrac%7B1%5Ccdot%203%2B2%7D%7B3%7D%5Cimplies%20%5Cstackrel%7Bimproper%7D%7B%5Ccfrac%7B5%7D%7B3%7D%7D~%5Chfill%20%5Cstackrel%7Bmixed%7D%7B2%5Cfrac%7B1%7D%7B3%7D%7D%5Cimplies%20%5Ccfrac%7B2%5Ccdot%203%2B1%7D%7B3%7D%5Cimplies%20%5Cstackrel%7Bimproper%7D%7B%5Ccfrac%7B7%7D%7B3%7D%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20%5Ctextit%7Bvolume%20of%20a%20rectangular%20prism%7D%5C%5C%5C%5C%20V%3DLwh~~%20%5Cbegin%7Bcases%7D%20L%3D%5Cfrac%7B7%7D%7B3%7D%5C%5C%20w%3D2%5C%5C%20h%3D%5Cfrac%7B5%7D%7B3%7D%20%5Cend%7Bcases%7D%5Cimplies%20V%3D%5Ccfrac%7B7%7D%7B3%7D%5Ccdot%202%5Ccdot%20%5Ccfrac%7B5%7D%7B3%7D%5Cimplies%20V%3D%5Ccfrac%7B70%7D%7B9%7D%5Cimplies%20V%3D7%5Cfrac%7B7%7D%7B9%7D)
The area of triangle ADE is probably half of triangle ABC, so the perimeter would be 15 units, and the area would be 45 units squared.
