Calculate the surface area of the rectangular prism. Show your work

Answer to #1:

Front: 6x4 = 24cm2

Back: 24cm2

Top:6x9=56cm2

Bottom: 56cm2

Left: 9x4=36cm2

Right: 36cm2

​

Total Surface Area = 228cm2

​

Calculate the surface area of the triangular prism. Show your work

Answer to #2:

Triangle #1: 6x5=30 2 = 15 cm2

Triangle #2: 15cm2

Rectangle #1:10 x5 =50cm2

Rectangle #2: 50cm2

Rectangle #3: 10x6 =60cm2

​

Total Surface Area = 190 cm2

​

5000 mg = kg

Answer to #3A:

​

​

​

5000 / 10 = 500 cg

500 / 10 = 50 dg

50 / 10 = 5g

5 / 10 = 0.5 dag

0.5 / 10 = 0.05 hg

0.05 / 10 = 0.005kg

5000 mg = 0.005 kg

12.4km = m

Answer to #3B:

​

​

​

​

12.4 x 10 = 124 hm

124 x 10 = 1240 dam

1240 x 10 = 12,400 m

​

12.4 km = 12,400 m

​

​

A Rubik’s cube has sides measuring 5cm. True or False: the total surface area would be 145cm2? Explain why.

Answer to #4:

FALSE!!

​

It’s false because the total surface area would be 150cm2.
