# Rhombus base

Calculate the volume and surface area of prisms whose base is a rhombus with diagonals u1 = 12 cm and u2 = 10 cm. Prism height is twice base edge length.

Result

V =  937.23 cm2

#### Solution:

$a^2 = (u_1/2)^2 + (u_2/2)^2 \ \\ a = 7.81 \ cm \ \\ V = (u_1 u_2 /2 )\cdot 2 a = u_1 u_2 a = 937.23 \ \text{cm}^2$
