It is impossible to answer this question because the question could refer to an object in 7-dimensional hyperspace or it could be an irregular heptagon (or other possible shapes in 3, 4 5 or 6 dimensions). In anything but 7-d space, its exact shape is indeterminate and so the area cannot be calculated. To understand the indeterminacy, a 2cm + 2cm + 2cm + 2cm shape could be a rhombus or a square, and these will have different areas. Without the angles, there is no way of knowing which.
24cm. cubed
3cm * 2cm * 1.5cm = 9cm3
An isosceles triangle
it is "1 == 2"
An iscoceles triangle, because two of the sides are equal but one is not. Please try to pay attention in class, silly. Hope this helps. ☺
Assuming this is a rectangular block, you are supposed to multiply the three numbers.
2cm*5cm*3cm=30cm3The volume of the cuboid: 2*5*3 = 30 cubic cm
2x3x2=12cm3
It could be 3cm by 2cm in size.
Mean = sum(X)/n = 15cm/5 = 3cm
