Question

What is the surface area of this? Please help me. Very urgent. Thanks!

Answer 1

`\huge\boxed{\sf 160\ cm\²}`

Explanation:

Area of the Square:

= Length * Length

Where length= 8 cm

= 8 * 8

= 64 cm²

Area of the Triangle:

= 1/2 (Base)(Height)

Where base = 8 cm, height = 6 cm

= 1/2 (8)(6)

= (4)(6)

= 24 cm²

Area of 4 triangles:

= 4(Area of triangle)

= 4(24)

= 96 cm²

Surface Area of Pyramid:

= Area of Square + Area of 4 Triangles:

= 64 + 96

= 160 cm²

`\rule[225]{225}{2}`

Hope this helped!
