From the textbook, I had to do pages 260-261 numbers 11,16,17.

Here's what I did.

1)Copy and complete the following table.

the 700 is supposed to be 1200, sorry for the mistake.

a) So this is what I did. I needed to find the height for the first one so I divided 70 by 7 and I got 10

then I divided 10 by 2 and got 5.

b)For the second one I did the same thing 1080/12 = 90, 90/10 = 9 12x9x10 = 1080

c) 1200/5 = 240, 240/ 15 = 16

16)Cindy’s aquarium stands 75 cm tall and

has a base that measures 1.2 m × 80 cm.

At one point during the initial filling, the

aquarium has a 12-cm depth of water in

it. Cindy needs to fill it to 15 cm from the

top before she adds the fish. Draw a

diagram and label the dimensions of the

aquarium. Determine how much more

water Cindy must add before she puts in

the fish.

v= l.w.h

v=75cm.80cm.12cm

v=72,000 cm3

17) contractor is excavating a rectangular

hole 10 m × 12 m × 3 m to pour the

foundation for a house. A dump truck

with a capacity of 9 m3 is used to haul

away the excavated soil. How many trips

does the truck need to make?

v= l.w.h

v=10mx12mx3m

v=360

360/9= 40

The truck made 40 trips

Good job Brandon. I liked the pictures you made but it would have been nice if you changed the colour of the important words in the questions.

ReplyDeleteGood Job Brandon. I liked how you explained everything. But to make your pictures more catchy you should've added colors, and you should've made the font size bigger so it doesn't look plain. Good Job.
