Answer:
1,512 cm³
Step-by-step explanation:
The general formula for the volume of a prism is:
V= Bh, where B = the area of the base and h = height of the prism
Given the dimensions of the smaller block as 9cm x 3cm x 7cm, then the dimensions of the larger block (double the dimensions of the smaller block) must be 18cm x 6cm x 14cm. Using these measurements:
V = (18)(6)(14) = 1,512 cm³
