526.50 cm3

C.

166.00 cm3

D.

687cm3

Correct Answer: 234.00 cm3

Explanation

Let x represent total vol. 2 : 3 = 2 + 3 = 5 3/5x = 351 x = (351 × 5)/3 = 585 Volume of smaller block = 2/5 x 585 = 234.00 cm3

Let x represent total vol. 2 : 3 = 2 + 3 = 5 3/5x = 351 x = (351 × 5)/3 = 585 Volume of smaller block = 2/5 x 585 = 234.00 cm3
