Quadrilateral 66294

Calculate the surface and volume of a quadrilateral prism if given: the area of the base is 40 cm square, the bottom of the base is k = 8 cm, and the height of the prism is 1.3 dm (the bottom is a rectangle)

Correct answer:

S =  418 cm2
V =  520 cm3

Step-by-step explanation:

S1=40 cm2 k=8 cm h=1.3 dm cm=1.3 10  cm=13 cm  S1=k l  l=S1/k=40/8=5 cm  S=2 (k l+l h+h k)=2 (8 5+5 13+13 8)=418 cm2
V=S1 h=40 13=520 cm3
