Answer:
74.4 m³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = area of triangular base × length
area of triangle = 0.5 × 5 × 4.8 = 12 m², thus
V = 12 × 6.2 = 74.4 m³
Answer:
56 cm^2
Step-by-step explanation:
Surface area is just finding the areas of each face in a figure. As we are given a net of a figure, it is much easier for us to calculate it.
Area of square base (side^2)
4^2 = 16 cm^2
Area of ONE triangular face (1/2 x b x h):
1/2 x 4 x 5 = 10 cm^2
Multiply that by 4 because we have 4 triangular faces: 10 cm^2 x 4 = 40 cm^2
ADD all the areas of triangles and square:
16 cm^2 + 40 cm^2 = 56 cm^2
