First, find the surface area of the bigger sides (there are 4 of them so what you get for one you will multiply by 4)

12 x 8 = 96

96 x 4 = 384

Then find the surface area of the smaller sides ( there are two small sides so multiply your answer by two)

8 x 8 = 64

64 x 2 =128

Then add both together

128 +384 = 512

Hope this helps :)

What decimal is equivalent to 4/5 + 0.05

UNO [17]

To answer this we will add, but before we add we will change 4/5 in to a decimal. to change ANY fraction into a decimal we have to divide the numerator by the denominator. lets do it:-

4/5
4 ÷ 5 = 0.8

Now lets substitute 0.8 for 4/5 and then add.

4/5 + 0.05
0.8 + 0.05 = 0.85

CHECK OUR WORK:-

0.85 - 0.8 = 0.05
We were RIGHT!!

So, the decimal 0.85 is equivalent to 4/5 + 0.05.

Hope I helped ya!! xD
