Metallic colored plastic is being injected into molds to manufacture small beads for a crafts supplier. One of these beads is comprised of attached congruent square pyramids, as shown below. 7 mm
6 mm
How much plastic is needed to make each of these beads?
A. 112mm3
b 504mm3
c. 168mm3
d84mm3

Volume of Beads = 84 mm³

Step-by-step explanation:

Given:

Side of base = 6 mm

Height = 7 mm

Find:

Volume of Beads

Computation:

Volume of Beads = Volume of a square pyramid

Volume of Beads = [1/3][Area of base][h]

Volume of Beads = [1/3][6 x 6][7]

Volume of Beads = 84 mm³

168

step-by-step explanation:

i am pretty sure that the answer is 168

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
