Answer:
25
Step-by-step explanation:
The answer is 2/5. (Do not brainliest)
Surface area define or calculate the exact space that each face of the said shape is taken up while the volume is how much space is inside the said object. The area use the unit that is squared because it only measured 2 face in the shape while the volume measures 3 faces in the object. an example of an area is a card board area, while the volume is the glass of water.
1 glazed and 2 others or 3 glazed and 0 others
1 x 3 x 3 + 1 x 1 x 1
9 + 1
10
Answer: 10
Consider one pyramid
Side length of base = 1.5cm and its height is 1 cm
Slant height of one of the lateral faces = sqrt(1^2 + 0.75^2) = 1.25 cm
Area of one of the triangular faces = 0.5 * 1.5* 1.25 = 0.9375 cm^2
There are 8 of these so the required surface area = 8 * 0.9375
= 7.5 cm^2 Answer
