Mato's rectangular prism's volume is
40
To find the volume of a Rectangular Prism it's:
Volume= Length x Width x Height
Draw a rectangular prism with the volume of 40.
Then just explain by showing how to solve for your prism's volume and then Mato's.
If you need anything else just ask!
3x + 1 is the length for one side. Do you also need to solve for x?
A) V= lwh ,so, V= 25cm*25cm*50cm= 31250 cm^3 shape
b) V=lwh,so, V=10cm*12cm*58cm= 6960 cm^3 shape
c) It is a) because the volume is much bigger.
