Applying triangle laws using sides and angles
Seth is using a large shoe box to store his baseball cards. The length and the width of the box are each 12 inches, and the height is 6 inches. Which of the following could be used to find V, the volume of Seth’s shoe box?
V = (6)(12)
V = (6 x 12)2
C V = (12)(12)(6)
D V = 4(12) + 2(6)
