The figure above shows a cement block of 36 cm x 20 cm x 9 cm with two 10 cm x 8 cm
openings. What is the weight of the cement block
to the nearest gram? (The density of cement is
1.7 gram/cm
cm)
A) 5,040
B) 6,048
C) 7,560
D) 8,568

Step-by-step explanation:

weight = (volume of block - volume of slots) x density of block

           = (30 * 20 * 9) - (2 x (10 * 8 * 9)) x 1.7

            = (5400 - 1440) x 1.7

           = 8,568

the answer is 0.3175 hope that you ^w^
