I'm pretty sure it's a rectangular prism I hope that helps.
Answer:
Mistake was at Step 5
Step-by-step explanation:
Going from Step 4 to Step 5 you're supposed to:
Division first: 2 + (10 / 2)
Then Addition: 2 + 5
Solution = 7
Step 5 did addition first then division when it is supposed to do division first, then addition
Answer:
The volume of the rectangular pyramid is 80cm³
Step-by-step explanation:
To calculate the volume of a rectangular pyramid we have to use the following formula:
v = volume
w = width = 8 cm
l = length = 6 cm
h = height = 5 cm
v = (w * l * h) / 3
we replace the values that we know
v = (8cm * 6cm * 5 cm) / 3
v = 80cm³
The volume of the rectangular pyramid is 80cm³
Those are mixed fractions, so first you have to make them improper fractions, multiply the whole times the denominator and add the numerator, that will be you new numerator, then copy your denomminator.
81/8 + (29/8 + 23/8) Since they already have the same denominator use order of operations to proceed, 81/8+57/8 = 138/8 =17 2/8 = 17 1/4
Expression: -3 + -2/-5
Exact form: -13/5
Decimal form: -2.6
Mixed number form: -2 3/5
