Answer:
Length A: 5 ft
Width B: 4 ft
volume = 88 ft³
Step-by-step explanation:
Length A: 8 - 3 = 5 ft
Width B: 8 - 4 = 4 ft
<u>Volume</u>
The easiest way to calculate the volume is to split the trough into two rectangular prisms. (imagine drawing a horizontal line from the internal corner of A and 4ft to the left 8ft side).
Volume of a rectangular prism = width x length x height
Volume of rectangular prism 1: B x 8 x 2 = 4 x 8 x 2 = 64 ft³
Volume of rectangular prism 2: 3 x 4 x 2 = 24 ft³
Total volume = 64 + 24 = 88 ft³
Answer: A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Step-by-step explanation:
4b+21=-3b+21+7b
4b+21=4b+21
it means that the expression shows an identity
Answer:
C. 8
Explanation:
The ones place is where “7” is. The tenths place (in the case is where 5 is) determines what the ones place rounds up to.
Rules for rounding:
5 or above, round the number up.
4 or less, number stays the same.
Step-by-step explanation:
Shape A is flipped horizontally onto the x-axis
The new shape is mirroring Shape A
